摘要基坑工程是一个综合性的岩土工程问题，涉及到众多学科领域，基坑工程的设计不但需要岩土工程方面的知识，而且要有结构工程方面的知识。在基坑工程中，设计和施工是不可分割的，设计的情况需要和实际情况相符合才行，这样才能够保证设计的可靠性。基坑工程的设计需要安全可靠、技术可行、经济合理、施工便利，既要保护环境，控制安全，也要保证工期。要根据所在的地质条件、水文条件、环境条件，选择合理的方案。51232

     拟建工程是淮安市万达广场一号位于江苏省淮安经济开发区境内，宁连公路与237省道交接处东侧，西邻规划山阳湾路，东邻规划丹山路，南邻规划福地路，北邻规划长乐路，本工程±0.00相当于黄海标高+11.40m，所用标高系统为吴淞绝对高程系统。

    通过对周围地质水文等条件的分析，本着安全可靠、技术可行、经济合理、施工便利的原则，基坑工程采用水泥土墙和天然放坡的结构，先进行水泥土墙的手算，然后运用理正深基坑软件进行电算校核，最后绘制结构施工图。

Abstract

Excavation engineering is a comprehensive geotechnical engineering problems involving many disciplines。The designation of Excavation engineering not only requires Geotechnical Engineering knowledge, but also structural engineering knowledge.In the pit Excavation engineering,The designation should be consistent with the practical so as to ensure reliability of the designation.Excavation engineering designation requires the situation which owns secure, reliable, technologically feasible and economically reasonable, construction convenient, both to protect the environment, control security, but also guarantee durations.We should choose a reasonable solution according to the geological conditions, hydrological conditions, and environmental conditions.

The proposed project is located in Huai'an Wanda Plaza One Huai'an Economic Development Zone, Jiangsu Province, territory, Lianyungang Highway junction with the east of Highway 237 , west of  planning Sanyo Bay Road, east of Planning Dan Road, south of the blessed path planning , north of planning Changle Road. The project ± 0.00 is equivalent of the Yellow Sea elevation +11.40 m,and elevation systems used Wusong absolute elevation system.

By the analysis of surrounding geological and hydrological etc conditions, adhering to the principle of safe and reliable, technologically feasible and economically reasonable, convenient construction, Excavation engineering adopts cement walls and natural grading structure.What’s more ,firstly we use hand count of cement walls then take advantage of Rationale for deep excavation software Computer check,lastly create working drawings.

Keyword: foundation pit; Bracing structure; Cement walls; Natural grading
