      摘要
      在现代建筑中,钢板桩这种施工方法应用的也比较多,主要用于柔软低级地基开挖,使用液压式振动锤、起重机等设备把钢板桩打入土里,作为临时支挡材料,使用后再反向拔出的一种施工方式。主要特点在于结构形式对称,便于重复
      使用对节约利用资源方面前景乐观。
      本次毕业设计分三个部分,包括基坑的支护设计、基坑施工和设计图纸三大部分;首先基坑的支护设计,通过方案和地质环境的对比,采用钢板桩支护。首先基坑支护设计根据不同土层的信息及地下水位,算出每层土质的主动土压力、被动土压力以及水压力,通过不同钢板桩的嵌入深度的计算,最终得出一个满足该地质的钢板桩嵌入深度。然后根据基坑设计规范,计算钢板桩的坑底隆起稳定性验算、抗渗流验算以及基坑降水计算,最后通过基坑设计软件---电算,来验证之前手算数据的可行性。其次是基坑施工,涉及施工前的准备工作、基坑降水、钢板桩的打设、基坑开挖以及基坑的监测,在施工过程中会遇到各种问题,如打设钢板桩转角合拢、钢板桩打入的垂直度、钢板桩引拔时阻力较大等,钢板装施工时应考虑怎样预防这些问题的发生,如何采取相应的措施。最后是施工图纸,根据设计施工规范绘制了基坑平面图、施工总平图、基坑降水布置图、基坑支护剖面图、基坑监测平面图等等。

      This time my graduation design in two parts, including the foundation pit supporting design and the construction of the foundation pit of two parts; First foundation pit supporting design, through the solution and the comparison of geological environment, using the steel sheet pile support. First foundation pit supporting design according to the information of different soil layer and underground water level, work out every soil layer of active earth pressure and passive earth pressure and water pressure, through the calculation of different embedded depth of steel sheet pile, eventually satisfies the area is a qualitative steel sheet pile embedded depth. Then according to the foundation pit design specification, calculation of steel sheet pile uplifts of calculating stability, anti seepage calculation and calculation of foundation pit precipitation, finally through the foundation pit design --, computer software, to verify the feasibility of the numerical data before hand. Followed by the construction of foundation pit, involving the preparation work before construction of the foundation pit precipitation, steel sheet pile, foundation pit excavation and foundation pit monitoring, various problems encountered in construction process, such as the driven steel sheet pile corner folded, the perpendicularity of the driven of steel sheet pile, steel sheet pile, such as when pulling resistance is bigger, steel construction when loading should consider how to prevent the occurrence of these problems, how to take corresponding measures.
