摘    要:定向钻穿越技术自20世纪80年代引进以来,在管道穿越方面得到了广泛采用,到目前为止,已成功穿越大小河流上百条。随着大口径长输管道的兴建,定向钻穿越在某些特殊的工程地质和水文地质条件下,有引发塌陷坑、地面沉降和管涌等环境地质问题的潜势,为此,对可能产生这些环境地质问题的机理进行了分析。

关 键 词:定向钻穿越  油气管道  环境  地质  机理

Abstract:The horizontal directional drilling technology, introduced into China in the 80's of 20 century, is effectively and widely used in pipeline crossing, and so far nearly a hundred rivers have been successfully crossed. With the construction of large diameter and long distance pipelines, the horizontal directional drilling has a possibility to initiate several serious geological problems, such as sinking, surface settlement and gushing under some special engineering geological and hydrogeological conditions. The article makes overall analyses on the mechanism of these problems.
Keywords:pipeline  crossing  horizontal directional drilling  environmental and geological problems  mechanism  analysis
