以西安市某深基坑工程为例，运用FLAC3D软件对该基坑最危险的一段桩锚

Taking a deep excavation in Xi'an, for example, the use of FLAC3D software simulation of the foundation pit of the most dangerous period of the pile anchor support. By horizontal displacement value foundation settlement value with the top edge of the foundation analysis, and compared with the actual value monitoring, the pit is considered safe, but compared to the specification values, values ​​which monitor the analog value is relatively small, the pit design is too conservative. Therefore, to optimize the pit design, and ultimately get an optimal support scheme.

Taking a deep pit project in Xi'an as an example, using FLAC3D software to simulate the most dangerous section of pile anchor support in the pit. By analyzing the deep horizontal displacement value of the pit with the settlement value of the top edge of the pit, and comparing it with the actual monitoring value, the pit is considered to be safe, but compared with the standard value. Its simulation and monitoring value are relatively small, the pit design is too conservative, so the pit design is optimized, and finally get an optimal support scheme.
