摘要
固体废弃物填埋场填埋库区地基不均匀沉降是控制填埋场污染问题的关键问题之一.本文根据郴州某地区填埋场建设过程中的岩溶洼地软弱下卧层处治案例, 通过三维地质建模研究软弱下卧层的分布特点及范围, 并采用有限元方法分析库区基底沉降, 通过方案对比提出采取变形协调方式控制地基不均匀沉降, 以期为今后类似工程提供参考经验.
The uneven settlement of the foundation of the solid waste landfill is one of the key problems in controlling the pollution of the landfill. Based on the treatment case of the soft lower lying layer in the karst depression in the construction of a certain area in Chenzhou, this paper studied the distribution characteristics and scope of the weak substratum through three-dimensional geological modeling, and used the finite element method to analyze the foundation settlement in the reservoir area, and the deformation coordination method was put forward to control the uneven settlement of the foundation by means of the scheme comparison. It is hoped that this study can provide reference experience for similar projects in the future.
