( s ) weathering and unloading action which are the two main exogenous process is active in epigenetic - surface . so , although one is different with the other , they are associated with each other closely and are cntrolled by geostress and seepage fields . in fact , weak weathered zone corresponds to weak load - off one , strong weathered zone corresponds to strong load - off one in virtue of result of this dissertation . ( 6 ) rock mass is a geologic body which is composed of rock and structural plane . and under the condition of geostress . temperature and seepage fields , correspondingly . studying weathering should pay attation to the aspects of rock , structural plane and fields . according to this . the author subdivises rockmass weathering into rock weathering and structural weathering , ulteriorly , the dissertation studies rockmass weathering from three aspects as follows : ? ock weathering : aberrance degree of mineral and physical mechanical performance of weathered rock ; ? e have already knew that weathering action damage the integrity of rock mass , but few applies it to engineering practice . the dissertation is based on trend o 本文研究结果为弱卸荷与弱风化大致对应、强卸荷与强风化大致对应； ( 6 )岩体是由组成它的岩石与缺陷赋存于一定环境场中的地质体，据此本文将岩体风化细划为岩石风化与结构面风化，并进而将表征岩体风化的指标相应地归结为三个方面来加以研究并应用于工程实践，这就是：对于岩石风化，主要为矿物的变异程度与风化岩石的物理力学性能研究：虽已认识到风化作用破坏了岩体完整性，但将该理论应用于岩体风化分带却不多见，本文即从浅表部位硬性结构面间距、条数、迹长、块度等随远离临空面的变化规律来研究岩体风化分带：不同风化、卸荷程度的岩体实际处于不同环境场中，弹性波速变化与特定环境场相对应，因而是反映岩体风化、卸荷的综合因素。
In part three , according to the viewpoint of system , giving consideration to all kinds of condition of forming hillslope debris flow , taking five indexes as follow : the shape index of ditch , the mean value of greatest precipitation within 24 hours , the developing degree of unstable mass , the mean depth of loose " accumulated clay and the rate of plant cover , applying fuzzy mathematics , the paper designs a suit of scheme about judging hillslope data 第三部分，依据系统的观点，全面兼顾了山坡泥石流形成的各种条件，选取沟谷纵剖面形态指数、最大24小时暴雨均值、不良地质体发育程度、松散堆积层平均厚度和植被覆盖率五个指标，运用模糊数学方法在室内设计出一套山坡泥石流沟与非泥石流沟的判定方案。然后以野外实例数据进行检验，结果表明本方案分辩率较高，为84 . 6 ，且偏于安全一侧。
This paper proposes a method for optimizing the parameters of geometry system . based on the ray tracing for the built - model , discussing and analyzing the parameters of geologic aim such as the bin size , calculating the fold of aim layer ' s common reflection point , comparing the fold of crp with the fold of common mid - point , the geometry system ' s parameters are adjusted to improve the low fold bins , the quality of data collection and effect of exploration 本文提出了首先建立目标地质体的数字模型，根据射线追踪正演分析，目标地质体的参数分析(面元分析等) ，统计求取复杂地质模型目标层真正的共反射点覆盖次数，比较cmp面元与实际crp面元的覆盖次数差异， cmp道集对应的共反射点面元分析，针对覆盖次数较低的目标层面元调整和优化观测参数，提高目标层的采集质量和勘探效果。
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。
However geological information is fully recorded in the remote sensing image , which made it possible for the choosing of this area as a dissection point to extract complex structural information of orogenic belt in west china . taking fully advantage of multi - band image richly bearing concealed geological information in combination with remote sensing analysis and structure analysis , to anatomy the supracrustal composition and structure of orogenic belt with the regional linear structures and their partitioned block and schistous geological masses as the macro - frame ( in corresponding to structure units and structure segments ) and with the rock masses , structure - rock assemblages , line - featured and belt - featured structures as well as penetrative and non - penetrative foliation ( primary stratum and trans position layering ) and folds as the texture and structure elements . the methods of how to distinguish granulite > ductile - shear zone , imposed fold , different deformed belts - 因而，本文选择这一地区作为我国西部地区从遥感图像上提取造山带复杂结构构造信息的解剖区，充分利用遥感图像多波段反映物质属性的特点和图像处理提取隐含信息的优势，采用遥感解析?构造解析相结合的研究方法，以区域线状构造及由它划分的块状、片状地质体为宏观骨架(对应于构造解析划分的构造单元、构造均匀区段) ，以地质体中的岩石岩体、构造岩石组合，线状、带状构造，透入性、非透入性面状(原始层理、新生面理)和褶皱等构造作为用于解析的结构构造要素，进行造山带表壳组成和结构构造解析研究。
