摘要
结合项目设计经验,阐述阶梯式防沉板在导管架安装中的应用。根据导管架场址表层土特性,分别介绍阶梯式防沉板在砂土和黏土中的设计要点。针对不同的表层土特性对阶梯式防沉板的设计给出建议:当表层土为承载能力较强的砂土时宜选用面积较小的三角形防沉板;当表层土为承载力较差的黏土时则需选用面积较大的矩形防沉板;对于水平度较差的黏土场址还应辅以局部场址处理的方法。
Based on the project design experience,the application of stepped mud-mat in jacket installation is expounded.According to the characteristics of the surface soil of the jacket site,the key points of the design of stepped mud-mat on sand and clay are introduced respectively.Some suggestions are given for the design of stepped mud-mat according to different surface soil characteristics.For the sand with strong bearing capacity,the triangular mud-mat with smaller area should be selected.For the clay with poor bearing capacity,the rectangular mud-mat with larger area should be selected.For the clay site with poor levelness,the local site treatment method should be used.
