市政建设中基坑工程施工技术浅析

Elementary Analysis of Foundation Pit Engineering Construction Technology in Municipal Construction

随着现代城市市政建设的发展与进步,为了充分利用有限的土地资源,增加空中和地下空间的使用成为城市建设的必然选择,各类基坑工程在城市建筑中大量涌现。在城市基坑施工技术积累丰富经验及涌现各种新技术的同时,基坑工程坍塌的事故也频频发生,不但给国民经济造成巨大的损失,还危及到人民生命财产安全。城市基坑工程施工技术的总体原则是安全、经济、可靠与方便。该文结合某城市深基坑工程实例,论述了基坑工程关键施工技术,以期给市政工程建设提供工程参考。

With the development and advancement of the modern urban municipal construction and in order to fully utilize the limited land resource,the increment of using the air space and underground space become the inevitable choice of city construction,and various foundation pits are used in the city construction in the gross.The accidents of pit collapse frequently happen while the rich experience of urban pit construction technology is accumulated and various new technologies come forth.These accidents will not only bring the huge loss to the national economy,but also endanger the people's life and the property security.The general principle of the urban foundation pit engineering construction technology is safe,economic,reliable and convenient.The article discusses the key construction technology of pit engineering by a case of deep foundation pit construction in a city,which is expected to provide the reference for the municipal engineering construction.
