关于钢管桩与土钉墙联合支护设计的研究

The unite retaining design of steel tube pile and soil-nail wall

主要介绍钢管排桩与钢管土钉的联合作用设计原理,及在高地下水位且排水困难、支护结构尺寸受限制、淤泥质砂层为主的复杂不良地质中的应用实例,支护结构具有施工方便迅速、节省造价、路面沉降小的优点。

The text mainly introduce the tmite effec＇t design theory of steel pipe arrange pile and soil nailing, and a practical case in high underground water level, drainage difficulty, restricted struicture size and mostly silt sand complex bad geology. Retaining structure has advantages of convenient rapid construction, save cost and little pavement settlement.
