摘要 本文在概述浙江沿海沉积淤泥质软土地质的特殊性的同时,对长距离定向钻在浙江沿海沉积淤泥质软土环境中的穿越难点进行了细致分析,并根据穿越施工作业的不同阶段,给出了相应的解决方案,同时结合实例,采用"Peck"计算公式及有限元模拟方法,对长距离定向钻在穿越过程中对软土环境的影响进行了计算分析. In this paper,while summarizing the particularity of depositional silty soft soils along the coast of Zhejiang Province,a detailed analysis of the difficulty of long-distance directional drilling in silty soft soils there has been carried out.The corresponding solution was given.At the same time,using the"Peck"formula and the finite source simulation method,the influence of the longdistance directional drilling on the soft soil environment during the crossing process was calculated and analyzed.
