Earth excavation method for deep and large foundation pit
The invention provides a deep and large foundation pit earth excavation method. The deep and large foundation pit earth excavation method comprises the following steps that S1, influence factors of foundation pit earth excavation are analyzed; and S2, according to the scale and the shape of the foundation pit, the earth excavation area is partitioned and partitioned in a skip mode, then the layering condition of earth excavation is determined according to the depth and the working condition of the foundation pit, after the earth excavation area is divided into areas, blocks and layers, earth excavation node acceptance check is completed, and therefore earth-rock engineering can be conducted. The earth excavation method for the deep and large foundation pit has the advantages that excavation can be conducted reasonably in a zoning mode, a blocking mode and a layering mode, the excavation efficiency is improved, meanwhile, the safety and stability of a foundation pit supporting structure can be guaranteed, the conditions of site soil texture and the supporting structure can be fully combined, a reasonable cushion layer arrangement mode is adopted, and constructed engineering piles are protected.
本发明提供一种深大基坑土方开挖方法。所述深大基坑土方开挖方法包括以下步骤：S1.分析基坑土方开挖的影响因素；S2.根据基坑规模及形状，以跳仓形式对土方开挖区域进行分区分块，再根据基坑的深度以及工况确定土方开挖的分层情况，将其划分为区、块及层后，即完成土方开挖节点验收，从而可以进行土石方工程。本发明提供的深大基坑土方开挖方法可以合理分区、分块、分层开挖，提高出土效率，同时不仅可以保证基坑支护结构的安全稳定性，还可以充分结合场地土质及支护结构情况，采用合理的垫层布置形式，保护已施工工程桩的优点。
