Abstract

Abstract The dynamic response of the retaining structures is a complex issue, and a major challenge in their design, especially under seismic loading conditions. So a reliable and efficient solution following a computational approach, closer to reality, is required to obtain satisfactory results. Hence, this study came to clarify the effectiveness of the PLAXIS 3D program in predicting the performance, accuracy, and reliability of retaining walls. A case study of placing compressed materials as the backfill of the retaining wall soil is analyzed in this study using PLAXIS 3D software. The results are compared with the experimental results and the results of PLAXIS 2D software. The purpose is to predict the performance of retaining walls under seismic loads. As a result, the research stated that the displacement with time was less than the results recorded depending on the program PLAXIS 2D. According to the comparison of the different analytical tools, the researchers concluded that the adoption of the PLAXIS 3D program gives results that are closer to reality, more accurate, and more reliable.

PLAXIS软件预测支挡结构在地震荷载作用下的性能

挡土结构的动力响应是一个复杂的问题，是挡土结构设计的主要挑战，特别是在地震荷载作用下。因此，为了获得满意的结果，需要一种可靠、高效、符合实际的计算方法。因此，本研究阐明了PLAXIS 3D程序在预测挡土墙性能、准确性和可靠性方面的有效性。采用PLAXIS 3D软件对挡土墙土充填压缩材料进行了实例分析。计算结果与实验结果和PLAXIS 2D软件计算结果进行了比较。目的是预测挡土墙在地震荷载作用下的性能。因此，研究表明，位移随时间的变化小于根据PLAXIS 2D程序记录的结果。通过对不同分析工具的比较，研究人员得出结论，采用PLAXIS 3D程序得出的结果更接近现实，更准确，更可靠。
