基于SRC-CAD系统的水下土工布施工工艺研究

水下土工布施工是海上疏港公路路堤施工的先行工作,在海底涂面铺设过程中面临着海底地形不明确、海上船只定位难以及海底水流造成土工布的漂浮或折叠等问题,其施工质量和进度严重制约着疏港公路路堤施工后续工作的开展。基于SRC-CAD计算机辅助系统的海底地形云图显示技术和海上定位技术,结合已有的施工方案对水下土工布施工工艺的关键问题进行深入研究。研究结果表明:利用海底地形云图显示技术能为土工布铺设前的海底清理、整平等工作提供依据;采用边铺边压碎石的方法能最大限度地减小土工布受海底水流的影响。

Research on Underwater Construction Technology of Geotextile Based on SRC-CAD System

the underwater geotextile construction is the leading work of the sea port road embankment construction,due to seafloor topography is not clear,the ship positioning,the floating or folded of geotextile caused by subsea current,and other difficult issues,the construction quality and schedule of geotextile seriously restricts the development of port road embankment construction work.Combined with existing key issues on the construction technology of geotextile under water,this paper conduct a deep going study of the construction scheme based on Seabed terrain contour SRC-CAD computer aided system of display technology and marine positioning technology.The results show that：the use of seabed terrain image display technology can provide the basis for the cleaning of seafloor before geotextiles laying;Construction of crushed stone can be used to minimize the effect of flow on geotextile.
