船坞衬砌墙渗漏原因分析及对策

Cause and countermeasure of leakage on dock lining wall

采用地下连续墙或混凝土板桩墙的干船坞墙体,其外衬砌墙容易出现裂缝,并最终导致裂缝漏水,严重的甚至导致漏砂,影响结构的正常使用。结合具体工程的实际情况,分析衬砌墙裂缝产生的原因,并提出衬砌墙裂缝的预防措施及裂缝出现后的处理措施。

For the dry dock wall, which is made of the underground continuous wall or concrete sheet pile wall, cracks easily occur on its outside lining wall, which lead to water leakage, and even sand falling, and finally affect the function of the structure. Based on the actual engineering execution, thia paper analyzes the causes of cracks on the lining wall, and gives some advice on prevention and treatment of cracks on the lining wall.
