The bank landslide of reservoir is a most important engineering geological problems that come into being with the hydropower station being constructed . lots of studies have been done during past years . however , the theories and methods of research have seldom been progressed , as this or that kind of condition confines 水库库岸稳定性问题是人类工程活动改变地质体的地质环境而产生的重大工程地质问题之一，过去对水库库岸滑坡做了大量的研究工作，但由于条件的局限性往往在理论和研究方法上很难有所突破。
Based on abroad consultations and studies on national and foreign related datum , mainly taking shenzhen luohu fracture zone for research object , and by means of analysis on locale monitoring datum analysis , laboratory routine rheopectic testing , finite element numerical simulation and appraisal of gis stability , a few of conclusions can be summarized as the following : ( 1 ) analyzing present and past geological reconnaissance datum and reports of stability appraisal in luohu jiancheng district and synthesizing a mass of crustal stress monitoring datum and huangbeiling faultage f8 monitoring datum , and combining closely with practical engineering activity in luohu district , characteristics of crustal stress distribution is deeply discussed , which has an important guiding meaning for studying region stability and underground structure safety in luohu district 本文在广泛查阅、研究国内外有关资料的基础上，主要以深圳罗湖破碎带为研究对象，通过现场实际监测资料分析、室内常规流变试验、有限元数值模拟以及基于gis的稳定性评价，可以得到以下几点结论： ( 1 )分析了罗湖建成区以前和现今的地质勘察资料、稳定性评价报告，综合大量的现今地应力监测资料和黄贝岭f8断层监测资料，紧密结合罗湖建成区的实际工程活动，深入探讨了罗湖区的地应力分布特征，这对于研究罗湖地区区域稳定性和地下建筑物的安全性具有重要的指导意义。
Abstract : based on the investigation of the engineering geological environment and the displacement monitoring of no . 2 landslide at jindong town , the landslide revival mechanism with the relationship of the landslide revival with the human s engineering activity which included mining gold , evening ground for building , ascending and descending of the reservoir water are discussed 文摘:在对广元市金洞乡号滑坡的工程地质、地质环境进行详细研究和对滑坡复活变形进行监测的基础上，论证金洞乡号滑坡复活变形与采金、建镇平场、库水消涨等人类工程活动之间的相互关系及其复活机制。
Because of the engineering geological happening , the magnitude losing have often taken place on the process of design actualizing and engineering building practicality running though the designing is provided with engineering geological investigation measure of the field on engineering exploitation activity of the subaqueous delta of yellow river 在黄河水下三角洲开发的工程活动中，尽管设计都是针对具体场地的工程地质勘察资料进行的，但在设计方案实施和工程构筑物实际运行中，常因始料未及的工程地质事件发生，造成巨大的损失。
To evaluate the mine engineering geological conditions and for making - up an engineering activity plan that guides the mine development , an engineering geological environmental analysis of aoshan mining area in nanshan mine , maanshan iron and steel co . was made . through rock property analysis , single factor analysis and comprehensive evaluation , the coordinability of various factors were determined 为评价矿山工程地质状况，指导矿山开发的工程活动规划，开展了马钢南山矿凹山矿区的工程地质环境分析，通过岩性分析、单因素分析及综合评价，得出各因素的可协调性结果。
Remanufacture engineering is the general designation of all techniques and activities for repairing and reusing worn machine parts , which can provide guidance to product design and management based on product whole life period . with the development of computer and robotics , remanufacture engineering is heading for automation and intelligence 再制造工程是以产品全寿命周期管理为指导,以优质、高效、节能、节材、环保为目标,以先进技术和产业化生产为手段,来修复或改造废旧产品的一系列技术措施或工程活动的总称。
At last , the paper interprets the geological background of the forming of landslides , and reveals the landform , stratum , lithology and geologic structure based on the etm + image . and also , the paper interprets the location and distribution of the specific disaster bodies based on the quickbird image . through the analysis of the extracted information , the paper considers : the geologic structure of fengjie county is complex , and lithology is crashed ; the terrane in the canyon segment is fairly stable ; the terrane in some segments of the southern bank will be less stable after the water is stored , because the rock is in the same direction and is apt to slip with human project 最后在etm +图像上对滑坡发育的地质背景进行解译，提取了地形、地层岩性、地质构造等信息，在quickbird影像上详细地圈定了滑坡灾害体的实体位置及发育范围，通过对所提取信息进行分析，本文认为，奉节县地质构造复杂，岩性破碎；峡谷段岩层稳定性较好；南岸部分地段为顺向岩层分布区，人类工程活动容易诱发顺层滑坡，蓄水后库岸整体稳定性下降。
( 3 ) according to the actual geology situation in the material field , use the " alternation " principle of the value engineering analysis methods , and then find a better construction method to satisfy the requirement of rock - fill material , through using chamber blasting to substitute muffling and using an - fo to substitute ammonium nitrate explosive , and then huge economical benefits were gained , for example , the unit cost of its rock - fill material reduced from 11 . 77 m3 to 7 . 17 / m3 , and directly reduced the total cost by 4 . 26 million of cost ( : 3 )依据料场的实际地质情况，通过价值工程活动，利用价值分析的“代替”原理，在满足堆石料功能不变的条件下，采用洞室爆破代替深孔梯段爆破，采用按油炸药代替钱梯炸药，使得堆石料的开采成本显著降低，从投标价的h . 70元/ m3降低到7 . 17元/ m3 ，降低了4 . 53元/ mj ，以上坝堆石料94 . 2万m “计，直接降低成本426 . 75万元，产生了巨大的经济效益。
