摘要
平板载荷试验是检测地基极限承载力的一种最直接、可靠的方法,然而其尺寸效应问题对检测结果带来了诸多的不确定性.利用有限元软件对天然地基平板载荷试验进行模拟,并主要针对承压板大小及硬壳层厚度所存在的尺寸效应进行分析.在实际工程中,应根据上部结构的基础形式、基础尺寸及基础埋深情况等确定合理的承压板尺寸,从而得到更为准确可靠的地基土强度及变形特性.
Plate load test is the most direct and reliable method to detect the ultimate bearing capacity of foundation.However,its size effect brings a lot of uncertainty to the test results.The finite element software is used to simulate the plate load test of natural foundation,and the size effect of bearing plate size and hard shell thickness is analyzed.In practical engineering,the reasonable bearing plate size should be determined according to the foundation type,foundation size and foundation buried depth of the superstructure,so as to obtain more accurate and reliable foundation soil strength and deformation characteristics.
