摘要
为研究大面积堆载对邻近建(构)筑物的影响机理与治理对策,结合应力隔离桩与地基加固在大面积堆载条件下的软土地基处理中的联合应用工程实例,应用数值模拟方法,分析了大面积堆载导致邻近建筑物发生地基事故的原因,深入研究应力隔离桩和地基加固的应用对邻近建筑物地基的应力和变形的影响机理。在此基础上,提出经济有效的治理对策,同时指出需要进一步研究的问题,可为类似工程实践提供参考。
Application of a surcharge load to soft soil ground results in immediate undrained lateral soil movement away from the load and induces additional stress into the adjacent ground; problems involving the respond of soft ground to surcharge have been the topic of much recent research. Based on the engineering application which uses the synthetic method of stress isolation and ground reinforcement to handle soft ground problem induce by the adjacent surcharge load, this paper employs the PLAXIS to analyze the stress distribution and deformation of ground; reasonable agreement between the result and the observing data, is found.
