摘要

通过无处理软土路基和搅拌桩复合地基的土工离心模型试验，探讨了路基沉降与时间的关系、搅拌桩对路基沉降控制的效果以及桩顶、桩底、桩侧不同深度处的应力分布和不同深度处的桩身应变，对京沪高速铁路路基处理措施的选择和复合地基的理论计算有一定的指导意义。

Abstract

Based on centrifuge experiment of nature foundation and mixing pile composite foundation

foundation settlement varying with time

effect of mixing pile on foundation settlement control

stresses of different depths of pile and soil

and vertical strains along the piles varying with time are discussed. The result is useful for selection of foundation improvement methods for Beijing to Shanghai high speed railway and for theoretical calculation of composite foundation settlement.
