深层搅拌桩-钻孔灌注桩组合支护结构设计施工

Design and Construction for Combined Bearing Structures of Deep Mixing Pile and Bored Filling Pile

通过某工程实例介绍深层搅拌桩－钻孔灌注桩组合式支护结构的设计和施工，包括围护方 案的确定、力学模型的建立及受力分析、深层搅拌桩及钻孔灌注桩挡土墙的设计与计算方法、施工 及监测问题等，最后谈了对基坑支护结构设计及施工的一些体会。

Based on an engineering, the main points of design and the attention points for construction have been figured out. The support scheme, mechanics model and mechanics analyzing, method of design, construction and monitor for bored filling pile and deep mixing pile restaining wall have been discussed. Finally, some suggestions about design and constuction for support of the foundation pit have been mentioned.
