【摘要】 形成链子崖危岩体的主要因素是双层结构的高陡边坡与夹层软化、断裂节理割切、长江深切的无侧限策略卸荷作用和煤层开采。后者是最重要的直接诱因，是防治工程应抓住的关键部位和主要矛盾。通过对＂拉＂＂挡＂＂削＂＂垫＂四种方案的分析比较，提出应采取以＂垫＂为主体工程的方案，对这一方案的布置和施工提供了初步意见。更多还原

【Abstract】 Main cause of Lianzi Cliff dangerous rock body is the high steep slop of double layer structure with softening of intercalary strata, cutting of faults and joints, unloading of gravity due to the deep cutting of Changjiang River, and coal bed mining. The coal bed mining is the most direct causefactor. so, it should be the key point in the controlling engineering. Based on the comparison of four methods: pulling, blocking, cutting and filling,the controlling plan with filling as the main treating measure is suggested. In addition, the preliminary idea about the arrangement and practice of the plan is put forward.更多还原
