摘要：本基坑工程“南汇医学院二期基坑围护设计”分为J区与H区进行基坑围设计。J区开挖深度为5.4m局部7.0m，基坑面积约为1580m^2，周长约170m ；H区开挖深度为4.0m，基坑面积约为5135m^2，周长约340m，两个区域采用不同的围护形式， J区采用SMW工法，H区采用水泥土重力式围护墙，熟练地运用软件对围护结构进行整体稳定、抗隆起、抗渗流等验算，并且自行计算典型剖面。通过围护结构的计算结果进行支撑布置和计算，并计算配筋。通过对J区和H区的各个剖面计算结果进行平面施工图的绘制，包括有：各个剖面图，两个区域的平面图，支撑布置图，立柱布置图，降水布置图。本次基坑围护图纸共计12张。36028

Nanhui MEDICAL Two Foundation Pit Design
Abstract: The excavation area is pided into J and H zone foundation pit design. Excavation depth J area of 5.4m partial 7.0m, pit area of approximately 1580m ^ 2, a circumference of about 170m; excavation depth H zone is 4.0m, pit area of approximately 5135m ^ 2, a circumference of about 340m, two regions using different forms of containment, J region using SMW method, H zone using cement soil gravity enclosure wall, skillfully use the software to envelope the overall stability, anti-bump, anti-seepage checking, and automatically calculates the typical sections. Layout and be supported by calculations envelope calculation and calculate reinforcement. Through the various cross-sectional area and the J H region results drawn flat construction plans, including: the inpidual sections, plans two regions, support layout, column layout, precipitation layout. The foundation pit drawing a total of 14.
Keywords: foundation pit design; steel cement mixing pile; cement soil gravity enclosure wall; steel support; precipitation and Monitoring
