| 摘 要： | 珠江河口整治工程中抛泥区围堰的构筑采用土工织物袋充填砂快速成堤,由于河口地区基础均为淤泥,且土体力学特性差异较大,围堰易于发生较大的沉降,甚至出现水平位移。通过围堰局部出现的沉降滑移特例,分析其原因,并提出处理方案。

| Abstract: | The cofferdam at dumpling site in Pearl River Estuary Regulating Engineering is formed quickly by geotextile bags filled with sand. Since the foundation at Estuary area is silty mud,and mechanical characteristics of soil mass differ greatly,serious settlement or even horizontal displacement of the cofferdam easily occurs. According to a case of settlement and displacement in local area of the cofferdam,this paper analyzes the reasons for settlement and displacement, and puts forward treatment schemes. |
