花岗岩残积土在我国东南沿海地区分布十分广泛，在闽粤两地花岗岩出露面积可达总面积的30%-40%，残积土层厚度可达20-35m，该地区许多重点工程和基础设施建设都以花岗岩残积土为重要地质环境和主要载体。东南沿海地区气候湿热，降雨充沛，雨水极易通过孔隙渗入土体形成渗流，工程建设过程中面临的强渗流场下花岗岩残积土安全稳定的技术难题，关系到城镇化进程中各类重点工程的成败，所以研究花岗岩残积土的渗流特性及基坑渗流变形具有重要的理论及现实意义。 本文以取自东南沿海地区的花岗岩残积土为研究对象，制作饱和重塑试样，采用SLB-1型应力应变控制式三轴剪切渗透仪、TST-55型变水头渗透仪等仪器设备研究了花岗...Granite residual soil in the southeast coastal areas of China is widely distributed, in Fujian and Guangdong granite exposed area reach 30% -40% of the total area, residual soil thickness reach 20-35m, many of the key projects and infrastructure construction in the area are dominated by granite residual soil as an important geological environment and the main carrier.
