| 中文摘要:重庆巫山二郎庙移民小区滑坡勘察为三峡库区移民项目，地层复杂，采用传统方法进行勘察达不到滑坡勘察的目的。采用金刚石单动双管钻具+SM胶泥浆技术，取得了较好的效果，钻探台月效率由150 m提高到350 m，岩心采取率达85%～90%，而且取出了泥夹块石、滑面、软弱夹层、破碎带样品。 |

| Abstract:The landslide survey in Wushan Erlangmiao Transmigrant Village in Chongqing is one of transmigrant projects in Three Gorges Reservoir Area. The strata within the area are quite complex. Using the traditional drilling methods could not get the landslide investigation goals. While the double core barrel and SM glue mud came out of good results with increasing monthly drilling rate of 150 m to 350 m, core recovery of 85%~90%. The samples from broken rock belts, soft and weak interlayers, slide faces， and clay gravel can be take out by the method. |
