摘　　要：利用粘土原状土、重塑土和固化剂固-1加固的粘土的渗透特性试验结果,对比分析其渗透系数变化的规律,为工程设计和施工提供科学的依据。该试验的研究结果对于饱和粘土的加固和深基坑止水帷幕的设置有指导意义。According to the results of undisturbed and disturbed samples of Xiaoshan clay and the clay improvedwith stabilizer ZDYT-1 in different stabilizer mixing ratio and time through the laboratory test,the permeability ofthe clay is analyzed for reference to practical engineering. The testing study results are valuable for preventingwater curtain of deep excavation and consolidating soft clay.
