用灌注桩对改造工程进行护坡加固处理

CAST-IN-SITU PILES AS SOIL RETAINING STRUCTURE IN THE RENEWAL OF EXISTANT BUILDINGS

本文结合工程实例就老厂改造深基坑开挖的支护挡土灌注桩的设计及成孔理论进行了分析,给出了比较合理的灌注桩挡士支护设计方法,并通过经济比较,说明灌注桩用于老厂改造的挡土支护是经济、可靠的。

Through the design theory of the cast-in-situ piles as soil retaining structure and the stabilityanalysis of the pile hole presented in this paper combined with the deep excavation in the renewal ofexistant buildings, a suitable design method is recommanded. Both the economic comparison and themeasurment results illustrate that using cast-in-situ piles as the soil retaining structure in the renewalof existant buildings is reliable.
