软土地区大面积不规则深基坑支护设计实践与分析
摘要:针对软土地区深基坑支护的特点,结合工程实例,介绍了大面积不规则深基坑支护的重点和难点,并采用数值模拟软件分析基坑开挖对周边环境的影响。结果表明:对于超大面积、不规则深基坑,应用“时空效应”原理分区、分块开挖土方,并合理布置支撑体系对于控制基坑变形至关重要。
Abstract:For the characteristics of deep foundation pit support in soft soil area,based on engineering examples,this paper introduced the emphasis and difficulty of large area and irregular deep excavation support,and numerical simulation software is used to analyze the influence of excavation on surrounding environment.The results indicated that:for large area and irregular deep excavation engineering,it is very important to control the deformation of foundation pit by using the principle of "time-space effect" to excavate zonally and rational arrangement of support system.It has important reference value for similar excavation engineering.
