摘　　要：根据工程实例,利用基于有限差分理论的计算程序建立数值分析模型,对深基坑开挖与支护过程中临近基坑的建筑物地基沉降进行数值分析计算,得到了临近建筑物地基沉降的变化规律及沉降量具体数值,将数值分析结果与实测值进行对比,结果基本一致.研究表明,数值分析可以用于基坑开挖和支护过程中相邻建筑物地基变形的预测分析,为实际工程的设计和施工提供依据.Based on an Engineering Example,a numerical analysis model was established by finite difference program,and the settlement of adjacent building was simulated by computer which was induced by the deep foundation pit excavation,and the Change Law and specific values of Settlement were obtained. The simulation result was consistent with the test results. It shows that the method of numerical analysis can be used to the settlement prediction of adjacent building in the process of the deep foundation pit excavation,and it will provide the basis for the design and construction of practice project.
