[摘要]基坑在坑边竖向荷载的作用下,各项变形指标都应满足规范要求,才使得基坑安全可靠。在坑边超载的情况下,基坑安全性无法得到保障,重堆场加固使得基坑体系及土体变形满足规范要求。通过施工工艺、数值模拟、理论计算等方法验证加固措施的有效性及可行性。对大多数基坑可提供很高的借鉴。

Abstract: The foundation pit in the vertical load, the deformation index should meet the standard requirements, it makes the foundation pit safe and reliable. In the case of pit side, the safety of foundation pit can not be ensured, and the deformation of foundation pit and soil deformation can meet the standard requirements. The effectiveness and feasibility of the reinforcement measures are verified by means of construction process, numerical simulation and theoretical calculation. For most of the foundation pit can provide a high reference.
