基坑围护方法
摘要：
本发明提供一种基坑围护方法，在结构底板施工前先进行结构底板传力带施工。本发明提供一种基坑围护方法，在结构底板施工前先进行结构底板传力带施工，除了同样能在后期基坑混凝土支撑拆除后将应力传至地下结构以外，还可以利用底板混凝土传力带的自身重量与刚度，提高围护挡土结构的侧向刚度，控制基坑围护结构的变形，尽可能降低结构底板未完成前围护结构的日变形量，确保整个基坑工程的施工安全。
摘要（英）：

The invention provides a foundation pit enveloping method. Structural baseplate power transmission belt construction is performed before structural baseplate construction. According to the foundation pit enveloping method, the structural baseplate power transmission belt construction is performed before the structural baseplate construction, stress can be transmitted to the underground structure after foundation pit concrete supports are removed in the late period, gravity and rigid of a baseplate concrete power transmission belt can be further utilized, the side rigid of a soil baffle structure can be improved, deformation of a foundation pit enveloping structure can be controlled, day deformation amount of the enveloping structure can be completed to an utmost extent before the structural baseplate is completed, and construction safety of the entire foundation pit engineering can be guaranteed.
