Design Method of Mini-type Steel-pipe Composite Anti-slide Pile Based on Equivalent Method

摘要:

微型钢管桩工程应用中尚未形成合理的设计理论和实用设计计算方法，多依赖工程类比进行设计。基于等效法将微型钢管组合抗滑桩群与岩土体作为一个柔性抗滑挡墙，介绍了微型钢管组合抗滑桩的一般设计步骤，并结合某工程对微型钢管组合抗滑桩的设计计算方法进行了研究，对解决类似工程问题提供参考。

Abstract:

The reasonable design theory and practical design calculation method have not been formed in the engineering application of mini-type steel pipe pile, and the design mostly relies on engineering analogy. Based on the equivalent method, the mini-type steel pipe composite anti-slide pile group and the rock-soil body are taken as a flexible anti-slide retaining wall. The general design steps of the mini-type steel pipe composite anti-slide pile are introduced, and combined with a project, the design calculation method of the mini-type steel pipe composite anti-slide pile is studied, which provides a reference for solving the similar engineering problems.
