摘要
软土的物理力学参数是软基处理的依据,以珠海平沙新城勘察数据为基础,在系统分析室内试验和原位测试结果的基础上,总结了该区域软土的工程特性,研究结果表明:珠海平沙新城软土具有高含水量、高压缩性、大孔隙比、抗剪强度低、渗透性差、结构性强、欠固结、呈流塑状态等工程特性。总结了珠海深厚软土地基上工程建设的突出问题,结合平沙新城软土特性,提出了软土加固和不同类型工程软基处理的对策,研究成果可为滨海地区软基处理提供参考。
Physical and mechanical parameters of soft soil are the basis of soft foundation treatment.Based on the in-situ exploration data of Pingsha New Town project in Zhuhai,and the systematic analysis of laboratory test parameters,the engineering characteristics of soft soil in this area are summarized.The results indicate that the soft soil of Pingsha New Town project has several typical engineering characteristics,i.e.high water content,large void ratio,high compressibility,high liquid limit,high clay content,low shear strength,poor permeability,strong structure,and is under-consolidated and present flow plastic propertys.Based on the soft soil characteristics of Pingsha New town project,and several typical construction problems in Zhuhai,the treatment measures are presented for the reinforcement of soft soils in different engineering,which can provide some guidance for similar foundation treatment of soft soils.
