Design and practice of settlement-reducing embankment piles for soft ground treatment under large-area surface heaped load

Shanghai Xiandai Architectural Design (Group) Co., Ltd., Shanghai 200041, China

摘要

摘要: 基于20世纪70年代起瑞典、芬兰等北欧国家在软土地区的路堤下广泛采用传统路堤桩，以及20世纪80年代起中国上海等软土地区多层建筑下大量采用沉降控制复合桩基等两方面的工程经验，介绍了一种对大面积地面堆载下软土地基采用减沉路堤桩处理的新技术，该技术具有工期短、造价低和质量容易控制等显著优点。首先研究探讨了减沉路堤桩的一般概况和主要受荷与工作性状，然后提出了减沉路堤桩技术的主要设计步骤与方法，最后简要报导了采用减沉路堤桩处理的上海国际赛车场赛道地基工程实例。

Abstract: A new technique called settlement reducing embankment piles for the soft ground treatment under large-area surface heaped load is introduced based on the experience acquired from two kinds of engineering practice. One is the traditional embankment piles extensively used for road embankments in soft soil regions like Sweden, Finland and others in northern Europe since the 1970s, and the other is the settlement-controlled composite pile foundation used in great quantities for multistoried buildings in soft soil regions like Shanghai and other cities in China since the 1980s. Firstly, the general outline, loading and working behaviors of the settlement reducing embankment piles are given. Secondly, the major design procedures and methods for the settlement reducing embankment piles are proposed. Finally, the case history of the ground treatment using the settlement reducing embankment piles for the racing course of Shanghai International Circuit is reported.
