浅析2D工法地基处理技术

Analysis on 2D Construction Method of Foundation Processing Technology

复合地基技术在软土地基处理上已有着大量的应用研究,不同的处理技术适用于不同的条件。软基处理中最为常用的是粉喷桩复合地基,该法对于工期紧,软土性质较差的地基有着较理想的处理效果,但是粉喷桩在处理软土地基中常出现一些问题。粉喷桩与排水固结法有机地结合起来,成为一种全新的软土地基处理技术-排水粉喷桩复合地基工法(简称2D工法)。比较粉喷桩处理软土地基,这种技术有效地解决了传统地基处理方法遇到的问题。现在复合地基处理技术已经日趋完善,排水粉喷桩复合地基处理技术处于起步阶段,各方面的理论都不够成熟,而且还没有很好应用于工程实践中,在以后地基处理技术的完善中一定能得到进一步的发展和广泛的应用。

Composite foundation in soft soil treatment technology had already a lot of applied research,different processing techniques is suitabe for userin different conditions.Cement injection pile is most commonly used in the soft ground,this method has an ideal effect in the tight schedule project and the poor nature of the soft foundation,but in dealing with soft foundation cement injection pile has some problems.Cement injection pile and drainage consolidation method organically combined into a new soft foundation processing technology-drainage cement injection pile（2D construction method）.Compare with the cement injection pile,this technology effectively to solve the traditional problems encountered in the foundation approach.Composite processing technology has now become perfect foundation,drainage cement injection pile is in the initial stage,all aspects of the theory are not mature enough,but not well used in engineering practice,in the future the complete technology of foundation treatment will be able to further improve the development and wide application.
