摘要
桩基础是一种将结构荷载传递给土体的结构构件。在设计过程中,采用了许多经验方程来估计轴向桩承载力,并进行了桩荷载试验来验证设计。在印度尼西亚,普遍采用ASTM D 1143/D 1143M-07进行桩测试。中文代码jgj106 -2014是另一个可行的选择,最近越来越受欢迎。本文研究了用两种规范得到的荷载-沉降曲线。采用Mohr-Coulomb模型和硬化土模型对分析进行了模拟。与Mohr-Coulomb模型相比,硬化土模型得到了更为合理的荷载-沉降和荷载-超孔隙水压力曲线。其原因是莫尔-库仑模型不能很好地反映土的非线性行为。此外,结果表明ASTM D 1143/D 1143M-07和JGJ 106-2014的结果相当。因此,这两种方法可以相互替代。
Evaluation of ASTM D 1143/D 1143M-07 and Chinese Code JGJ 106-2014 for Pile Load Testing using Finite Element Method
Pile foundation is a structural element utilized to transmit structural load into the soil mass. During design processes, many empirical equations used to estimate axial pile capacity, and a pile load test is conducted to validate the design. In Indonesia, it is common to adopt ASTM D 1143/D 1143M-07 for pile testing. Chinese Code JGJ 106-2014 is another viable option, which has gained popularity recently. This study investigated the load–settlement curves obtained using both codes. The analyses were simulated using the Mohr–Coulomb and the Hardening Soil models. The Hardening Soil model yielded more reasonable load–settlement and load–excess pore water pressure curves than the Mohr–Coulomb model. The reason due to the Mohr–Coulomb model unable to capture the non-linear behavior of soil properly. Furthermore, the results showed that ASTM D 1143/D 1143M-07 and JGJ 106-2014 yielded comparable results. Hence, both methods could be substituted each other.
