某地区金融大厦土钉墙加桩锚基坑支护毕业设计（设计+图纸）

毕设基本摘要

摘   要
本次基坑工程设计主要从中基坑支护方法中选三到四种适合本工程的支护方法，然后再根据经济实用等条件选出一种最佳方案。作为本工程的最后拟定方案，在针对拟定的方案进行优化。具体到本工程中就是从土钉支护、桩锚支护、土钉墙加桩锚支护三种方案中选出经济实用的土钉墙加桩锚支护方法，最后在对土钉墙加桩锚支护进行优化。基坑工程一般包括支护工程和降水工程。本工程的降水工程根据地层条件及场地水文地质条件，最终选定轻型井点江水。做完支护和降水工作后，剩下的就是施工工艺等细节问题了。本基坑工程中的施工工艺包括了锚杆的施工工艺、成井施工工艺、土钉的施工工艺等。此外还有针对各个部分必要的质量检验和施工监测措施等。由此次设计可知，基坑支护方法的选择必须有理有据，主要是要经得起实践的检验。

Abstract
The excavation pit design from the main method of supporting three to four selected for the project support, then under the economic and practical conditions of a selected the best option. As the works of finalizing the program, developed in response to the optimization program。Specific to this project is from the soil nailing, pile-anchor, increase soil nailing pile-anchor three options were selected economic and practical soil nailing increase pile-anchor, Finally in the soil nailing increase pile-anchor optimization. Excavation works including general support engineering projects and precipitation. The project works under the precipitation formation conditions of the venue and hydrogeological conditions, and ultimately selected light wells river. Supporting finish the work and precipitation, leaving only details of construction technology issues. The excavation project, including the construction technology of the bolt construction technique, as well construction process, the soil nailing construction technology. There is also need to address all part of the quality of testing and construction monitoring measures. By the current design, we can see Foundation Pit method of choice must be justified, the main task is to stand the test of practice.
Keywords   Pile anchor；Soil nailing wall；Dewatering；Retaining and protecting for foundation excavation
