摘要
本文介绍了几个典型塑料排水板加固软基的设计、施工实例 ,对软土地基加固设计的固结系数选取及固结系数各向异性的特点、利用实测沉降曲线推算最终沉降量方法、加固深度等问题进行了讨论 ,通过对大量的现场检测资料反分析与实验室结果进行统计分析 ,提出了软土地基加固设计时固结系数选取的经验方法 ,分析了施工因素对固结效果的影响。
Some typical examples for the design and construction of soft soil improvement with prefabricated drains are introduced. The selection of the coefficient of consolidation for the design, the prediction of the final settlement based on the observation settlement curves and the depth of soil tre atment are discussed. Through the statistical analysis for the field testing dat a and the laboratorial testing results, the empirical method for the determinati on of the coefficient of consolidation is presented and the influence of constru ction factors to the consolidation effect are analyzed.
