There have been frequent geological disasters of landslides in the area of yangtze river three gorges , especially in the vicinity of lianziya hazardous rock mountain , where the constant deformation has been observed in the past several years , and the condition has become worse 长江三峡崩塌滑坡发育，崩、滑、流等地质灾害频繁，尤其是链子崖危岩体，近年来变形活动持续不断，逐年又加剧发展势头，存在发生大规模崩塌滑坡的危险征兆。
The in - situ stress in the slope is measured through relieving stress by overcoring . then the analysis that in - situ stress in slop influences the development and stability of dangerous rock is carried on by fracture mechanics . water pressure includes hydrostatic pressure and hydrodynamic pressure 通过对洪崖洞现场地应力的套孔应力解除，测试了危岩边坡的残余地应力，运用断裂力学的方法分析了地应力对危岩发育和对现有危岩稳定性的影响。
In this paper , a systematic study is carried out on the harness engineering of dingzhuang landslide and dangerous rock in the three gorges reservoir areas , which includes the evaluation of hazard , the stability analysis and the supporting system of landslide and dangerous rock , the monitoring system and the project management design 本文结合长江三峡库区重庆市丰都县丁庄裂口工业区滑坡及危岩，把滑坡与危岩这两种最为常见的地质灾害形式的治理作为一个系统工程进行了全面地分析研究，主要包括滑坡灾情评价、滑坡稳定性分析与工程治理技术方案、危岩稳定性评价及治理、治理工程监测方案及项目施工组织设计等几个方面。
Based on mechanics of fracture , and regarding thermal stress caused by temperature difference and static hydraulic pressure caused by fracture water as the main factors , the forecast of collapse period of dangerous rock is researched through different combination forms of fracture types , then a way to calculate collapse period of dangerous rock is provided 摘要以断裂力学为基础，以温度差引起的热应力及裂隙水引起的静水压力为主要影响因素，通过不同的断裂类型组合形式研究了危岩垮塌的周期，提供了一种计算危岩垮塌周期的方法。
In our country , no pull - out test of pressure - type anchor has ever been made in rock till now . in chapter 4 , consulting some pull - out tests of pressure - type anchor made by some civil researchers , contrast pull - out tests of pressure - type and tensile - type anchor in rock is designed in crag slope engineering in chongqing university 本文第四章在在参考国内一些单位已经进行的部分压力型锚杆抗拔试验的基础上，针对基于岩层的该类型试验还是空白的现状，结合重庆大学沿江危岩边坡治理工程设计了岩层中的压力型锚杆与传统拉力型锚杆抗拔力对比实验。
To solve this problem , the model of steady state water line in rock crack during the rain is built in cha5 . the author applies correlative seepage theories on this model to found the calculate method . then the practicality formula of hydrostatic pressure in dangerous rock is supplied 针对危岩静水压力计算严重偏于保守的情况，静水作用方面，本文通过建立降雨过程中的岩体裂隙积水稳态渗流模型，运用渗流的相关定理建立稳态水位的计算方法，进而提出静水压力的实用计算公式。
After researching the loads on dangerous rock synthetically , the author points out the development and collapse mechanism of dangerous rock : the geology foundations that forms dangerous rock are the constructional surfaces such as tectonic fracture 、 relief fissure , soft interlayer etc . . the developing of dangerous rock is due to release of in - situ stress in rock 、 aeolation 、 water erosion and root flerry . the main loads leading to collapse of dangerous rock are gravity , water pressure and earthquake force 在综合研究危岩上的各种作用之后，本文提出了危岩的形成和破坏机理：硬质岩体中构造裂隙、卸荷裂隙、及各种软弱夹层，结构面的的存在是危岩形成的地质基础；地应力卸荷、风化、流水侵蚀、植物根劈是危岩发育的主要作用；重力、水压力、地震力是危岩崩塌的主要荷载。
The study of collapse of dangerous rock is a focus among researches of various geological hazards . based on current domestic and foreign researches on dangerous rock and applying the hongyadong dangerous rock project in chongqing as the example , the following contents are researched : at beginning , the details of engineering geology on the area are introduced , including the conditions of engineering geology and hydrogeology 本文以目前国内外对危岩研究的现状为基础，以三峡库区地质灾害项目? ?重庆洪崖洞危岩综合整治工程为依托，进行危岩边坡的破坏和加固机理的研究，主要内容如下：论文首先介绍了洪崖洞地区的场地工程地质条件，包括工程地质和水文地质的详细情况。
An individual human existence should be like a river - small at first , narrowly contained within it ' s banks , and rushing passionately past boulders and over waterfalls . gradually the river grows wider , the banks recede , the water flows more quiltly , and in the end without any visible break , they become merged in the sea , and painlessly lose their individual being 上面的是一段对人生命的感悟，是说：一个人的生命应当象河流，开始是涓涓细流，受两岸的限制而十分狭窄，尔后奔腾咆哮，翻过危岩，飞越瀑布，河面渐渐开阔，河岸也随之向两边隐去，最后水流平缓，森森无际，汇入大海之中，个人就这样毫无痛苦地消失了。
