毕设基本摘要
摘 要
本次设计是对大学四年来土木工程专业知识学习的一次很好的复习、总结和控制，同时也是为让我的专业知识更加系统化、专业化，让我的设计达到一定的水准。
本工程位于武汉市宝丰一路血液中心院内，开挖面积约1559 ，支护周长近154m，基坑开挖深度为2.88~5.5m。
在满足安全的条件下，为最大限度地节约费用，针对个段特点采用分段优化支护形式，其主要支护形式有：（1）自然土放坡（2）型钢水泥土搅拌桩（3）水泥土墙。采用“m”法计算其嵌固深度，同时，通过整体稳定性，抗隆起验算、抗滑移验算、抗倾覆验算，来验证设计的稳定性和合理性。
关键词：基坑支护、土压力、稳定性、超载、嵌固深度
Abstract
The design of a four-year university to study civil engineering expertise of a good review, review and control. It is also to provide my expertise more systematic and professional, let me reach the design of a standard.
The project is located at the courtyard of Wuhan Blood Center in the first road of Baofeng, excavating an area of about 1559 m2and supporting perimeter nearly 154m, excavation depth of 2.88 ～ 5.5m.
In satisfiles under the safe condition, to maximize cost savings, a view of the characteristics of sub-optimal use of Support form, Supporting the main forms : (1) natural soil slope (2) Supporting pile (3) Soil nailing wall. Used the method of “m” to calculate its embedded depth, and though checking the overall stability of uplift resistance, anti-slip, Anti-overturning to verify the stability and rationality of design.
Keywords : Retaining and protecting for foundation excavation Earth pressure Stability Overloading Embedded depth
