宁波公路主枢纽段塘客运站基坑围护实录

Footing Groove Protection in the Construction of Duantang Bus Station

本文通过对宁彼公路主枢纽段塘客运站综合搂基坑场地条件及工程地质条件的分析，研究论证了水泥搅拌桩与钻孔灌注桩＋拉锚结构作围护在单体之间桩距离过近情况下的适用性、经济性和合理性，对水泥搅拌桩的优、缺点进行了探讨，并从施工角度阐述了影响围护质量的关键因素及需要注意的事项。

Through the analysis of the footing groove conditions and the engineering geological conditions of Duantang Bus Station Building - main hub of Ningbo highway network, the present paper discusses and proves the applicability, the economy and the rationality of cement treated composite foundation, drilling pile and pulled anchor structure as fender under the situation of over - close distance between unit piles. The paper also points out the advantages and the disadvantages of cement treated composite foundation and expounds on the key factors that affect the quality of fender as well as what needs our due note in construction.
