【摘要】 为研究西藏米林县县城工程地质情况,本文通过SH30-2型冲击钻机对现场地基土进行取芯钻探,在孔内进行标准贯入试验,并利用SM植物胶护壁,采用XY-100型钻机回旋钻进,对现场探孔情况进行详细说明,深入分析勘探场地岩层特性,并基于现场试验,说明地基土的工程特性,并对其进行分析评价,以期对该县城拟建工程提供一定的实用性建议。更多还原

【Abstract】 For the study of engineering geology condition of the mainling county of Tibet, this paper analyzed the SH30-2 impact drill is used to perform core drilling on the ground soil in the hole. It was carried out the standard penetration test, and used the SM plant rubber retaining wall to make a rotary drilling with the XY-100 drilling rig. It investigated the rock formation characteristics of the exploration site, and based on the field test, explained the engineering characteristics of the foundation soil, and analyzed and evaluate it, with a view to the county construction projects provide some practical advice.更多还原
