Instrumented Static Load Testing of Bored Piles for the Mega Transportation Hub of Beijing Sub-Central Station Xing Zheng Wu, Jun-Xia Xin Journal of Testing and Evaluation, 2025 Predesign static load testing of tentative piles is an important means to provide the basis for the pile foundation design before construction. This paper focuses on the tests performed on 12 instrumented superlong piles with a large diameter and high loading, intended for use in the comprehensive transportation hub project at Beijing urban sub-central station. The influences of pile construction techniques, such as base expansion and pile shaft and base grouting, on the bearing characteristics are discussed. Strains imparted in the reinforcement are measured by the vibrating wire gage installed along with the longitudinal reinforcement in these piles. Furthermore, the axial force against the depth of each test section is derived and the shaft friction resistance at the pile−soil interface is calculated. The results obtained for each pile indicate that the axial force at each test section increases as the load increases, but its magnitude gradually decreases from top to bottom under the same level of the load. In addition, the shaft friction resistance increases with the increase of the load, and the pile bearing capacity is significantly improved by applying relevant techniques such as base expansion and shaft grouting.
Experimental study of the effect of the inclination angle on mechanical characteristics and failure modes of layered sandstone Yongchuan Zhao, Bang Lv, Zhihao Xu, Xing Zheng Wu Quarterly Journal of Engineering Geology and Hydrogeology, 2025 This study investigates the effect of the inclination angle on the strength, deformation and failure characteristics of layered sandstone specimens with inclination angles prepared for uniaxial compression tests. The deformation distribution was analysed using digital image processing. The results reveal that the stress–strain curves of layered sandstone can be classified into distinct stages: initial compression; elastic deformation; inelastic and crack expansion; and post-peak failure. Compressive strength is significantly influenced by the inclination angle, displaying a right-biased ‘U’ shape across various angles, with the lowest strength observed at 75°. A similar left-biased ‘U’ trend is noted for elastic modulus and longitudinal wave velocity as the inclination varies. Digital image processing highlights significant differences in surface deformation with varying angles, primarily influenced by the bedding structure. Deformation concentrates in the bedding zones, identifying potential crack initiation and expansion. The failure mode is notably affected by the bedding structure, progressing from splitting tensile failure to single incline plane shear failure through the bedding structure and matrix, shear failure along the bedding structure, and X-conjugated shear and tensile failure as the inclination angle increases. This paper discusses the mechanical properties and failure mechanisms of layered sandstone based on these parameters and failure modes.
Comparative study on calculation methods for compressive strength of low strength aggregate concrete Xiaohui Wang, Jie Zhang, Wei Liu, Xingzheng Wu, Huiyun Li, et al. Aip Advances, 2024 The compressive strength of concrete with low strength aggregate volume fractions of 10%, 20%, and 30% was calculated using both the graphical analysis method and mesomechanics method. In the calculation method based on graphical analysis, three-dimensional random spherical aggregate models of concrete with different volume contents of low strength aggregate were established and sliced. The results show that the graphical analysis method can effectively calculate the compressive strength of concrete with different volume contents of low strength aggregate. In the graphical analysis method, the relative errors of the calculated compressive strength of concrete with low strength aggregate volume fractions of 10%, 20%, and 30% were 4.84%, 4.84%, and 6.43%, respectively. Three-phase concrete models composed of mortar, aggregate, and interfacial transition zone were analyzed through the method of mesomechanics. The calculation results of the mesomechanics method show that the compressive strength of concrete was controlled by low strength aggregate, and the calculated compressive strength of concrete decreased with the increase in low strength aggregate volume content. In the mesomechanics method, the relative errors of the calculated compressive strength of concrete with low strength aggregate volume fractions of 10%, 20%, and 30% were 1.36%, 1.74%, and 3.7%, respectively. It can be found that the calculation results of the mesomechanics method are closer to the test values and have smaller relative errors, which indicate that the calculation method of mesomechanics theory is superior to the method of graphical analysis.
Graphical analysis-based calculation method of concrete strength Xiaohui Wang, Jie Zhang, Xingzheng Wu, Xuan Zheng, Huiyun Li Aip Advances, 2024 This study established a three-dimensional random spherical aggregate model of concrete. Models with various volume contents of coarse aggregate were sliced, and slice areas were statistically analyzed. To study the effects of the coarse aggregate volume content and the interfacial transition zone (ITZ) strength on concrete’s compressive strength, a concrete strength calculation method based on graphical analysis was proposed. The ratio of crown area B to sectional area A of the spherical aggregate model was found to be close to 1.5. At the ITZ strength below 70% of the mortar strength, the increased volume content of coarse aggregate reduced the compressive strength of concrete, with the opposite trend observed at the ITZ strength exceeding 70% of the mortar strength.
Solving the geometric reliability index for a case involving multivariate random variables in the original physical space Rui‐kai Wang, Xing Zheng Wu Quality and Reliability Engineering International, 2023 An effective interpretation of the complex reliability theory will promote its application in engineering practice. Based on an algorithm for solving the geometric reliability index for cases involving two or three random variables in the original physical space, an advanced algorithm for multivariate random variables is further developed by using a hypersphere model and inverse Nataf transformation. The main components of the algorithm include the definition of limit state surface, the construction of a hypersphere model, the determination of probability density iso‐contour points, the identification of limit state of these points, and the definition of an actual reliability index. Several typical practical problems associated with two to five variables are analyzed, and the results are compared with those obtained using the first‐order reliability method (FORM) and the copula‐based sampling method (CBSM), thus validating the accuracy of the proposed algorithm. With the help of the powerful and open‐source R language platform, the visualization of a reliability index in low dimensions and the solvability in high dimensions are implemented, which makes the interpretation of reliability theory more intuitive.
