综合勘察方法在广东某电厂软土地基处理的应用

Application of Comprehensive Investigation Method in Soft Soil Foundation Treatment of a Power Plant in Guangdong

广东某电厂场地上部分布有较厚的软土,具有高含水量、高孔隙比、高压缩性、低承载力、低抗剪强度、低渗透系数等"三高三低"的特征,需采取地基处理方式进行加固。笔者通过分析统计室内土工试验结果,并结合勘察期间所采取的多种原位测试试验成果,为场地软土地基处理沉降的计算和后期地基处理效果的检测提供了有效而准确的岩土层参数,经项目软基处理效果的检验,依据综合勘察手段获取的软土参数准确有效。该成果可为同类的工程项目建设提供经验和借鉴。

The upper part of a power plant site in Guangdong is covered with thick soft soil,which has the characteristics of high water content,high void ratio,high compressibility,low bearing capacity,low shear strength and low permeability coefficient.It needs to be strengthened by foundation treatment.Based on the analysis and statistics of laboratory soil test results and combined with various in-situ test results adopted during the investigation period,the authors provide effective and accurate geotechnical parameters for the settlement calculation of soft soil foundation treatment and the detection of the effect of foundation treatment in the later stage.Through the test of the effect of soft foundation treatment in the project,the parameters of soft soil obtained by comprehensive investigation methods are accurate and effective.The results can provide experience and reference for the construction of similar projects.
