摘要
利用岩土工程的位移反分析法,并以偏压基坑的工程实例为基础,分别利用土体的HS,HSS模型,建立连续介质有限元正分析模型,得到基坑的位移场,然后与现场实际监测的位移场相对比,结果表明HSS模型相对HS模型与实际量测的变形趋势及规律更接近,并指出了偏压基坑变形及受力的特点,对类似工程有一定参考价值。
Using civil engineering displacement inverse analysis method, taking the bias foundation pit engineering as the case, it respectively uses HS and HSS model, establishes continuous media finite element positive analysis model, and obtains the displacement field of foundation pit. And then, it compares it to on-spot inspecting displacement field. Results show that： comparing to HS model, HSS model is close to actual measuring deformation trend and rules, and points out bias foundation pit deformation and stress characteristics, which has certain referring value for similar project.
