2、 support structure anchored by piles,To take full advantage of space resources, a part of slope or soil nailing, reduce the length of the pile, Effectively reduce the cost of the project and the difficulty of the construction. At the same time a large number of buildings around the pit, in order to
3、prevent precipitation caused by soil subsidence, landslides and other accidents, use a waterproof curtain approach;From the west,north and south side of the temporary buildings further away, using a programme: slope bored piles + + + oblique anchor soil cement mixing pile (Geshui curtain); close to the East from the adjacent buildings, inadequate venues slope, a second programme: soil nail wall bored piles. 3 目 录 0.0.绪论绪论(1 1) 1. 1. 工程概况工程概况 . .(1 1) 1.11.1 工程地质及水文地质概况工程地质及水文地质概况:(1 1) 2 2 支护方案一:桩锚支护方案一:桩锚. .(2 2) 2.1.2.1.计算土压力计算土压力. .(2 2) 2.22.2 根据根据 Pa2=Pp2Pa2=Pp2
