随着城市的发展,深基坑工程广泛地应用于城市建设,其相关前期模拟计算、中期施工控制及后期反馈重要性日益凸现。采用荷兰PLAXIS B.V.公司开发的岩土工程数值模拟软件,依据基坑开挖的实际步骤,对基坑开挖临空面及相关的支护结构进行了模拟,得到在排桩+锚索支护模式下基坑开挖后的变形以及应力特征,并与现场实际监测情况对比,对基坑的开挖控制有一定指导意义。
With the development of the city, deep foundation pit projects are widely used in urban construction. The importance of the relevant early-stage simulation calculation, mid-term construction control and post-feedback has become increasingly prominent. Based on the geotechnical numerical simulation software developed by PLAXIS BV in the Netherlands, according to the actual steps of excavation, the free surface of excavation and the related supporting structure are simulated, Mode after excavation of the deformation and stress characteristics, and compared with the actual monitoring of the scene, the excavation control of the foundation has a guiding significance.
