The investigation and study showed that caused by the influencing factors of unit of tectonics , structures of floor rock stratum , conditions of landform , seismic intensities , fault , thickness of malan loess , the distribution of seismic loess landslides is very asymmetrical , which mainly show shapes of patch , belt , line , and there are different development characteristics in different regions 现场调查显示，受大地构造单元、基底岩层结构、地形地貌条件、地震烈度、断裂构造和马兰黄土临空厚度等因素影响，地震黄土滑坡的展布形态较为复杂，在空间上分布很不均匀，常表现为片状、带状和线状展布，并在不同区域有不同的发育特点。
By comparing the aeromagnetic gradient data with the total field data , it can conclude that ; relative to aeromagnetic t , the gradient abnormality is more visible and it can be used to define the boundary of the magnetic bodies and the position of the fracture structure which could provide more information , especially the measured vertical gradient contain more abundant information than the calculated vertical 1st derivative 通过对航磁梯度和航磁总场资料的对比，发现航磁梯度场相对航磁t总场而言，异常更加明显；航磁梯度能更准确地确定磁性体的边界和断裂构造的位置，提供更多总场没有的信息，特别是实测的垂向梯度比计算的垂向一阶导数提供的信息更加丰富。
The research of large igneous rock province - ermei basalt extrusion - mantle plume shows that songpan - ganzi folded belt is a hopeful target for breakthrough of petroleum exploration , and the key issue is how to make well a coupling and optimization among its faults , structures , traps and reservoirs 根据地震测深、重、磁、电等的探查，发现该褶皱带深部有一低速高导层，而对大火成岩省峨眉玄武岩喷溢地幔柱的认识深化均表明，四川松潘甘孜褶皱带是可望获得油气勘探突破的靶区，重要的是断裂构造、圈闭、储集层的耦合与优化。
This paper has described in brief hydrogeological and geothermal conditions of longmen state grain depot in luoyang city , analyzed and interpreted integrated geophysical data obtained from the exploration locating of hot water and cool water wells over the same concealed fault in this area and , on such a basis , determined sites and depths of the drill wells 摘要简要介绍了洛阳市龙门国家粮库所在地水文地质和地热地质条件，分析解释了在该区同一隐伏断裂构造上进行热水、凉水井勘探定位时取得的综合物探资料，并据此确定了钻探井位及孔深。
The structural activity of offshore liaohe has the characteristics of multi - periods and multi - episodes . fault structures with different sizes , different styles and different strikes stack each other , forming composite structure system with extending and sliding features . this area is divided into 12 composite structural belts of five types 辽河滩海地区构造活动具有多期次、呈幕式的发育特点，众多不同尺度、不同样式、不同走向的断裂构造相互叠加，形成具有伸展走滑活动的双重性质复合的构造体系。
The regional deformation anomaly of medium - term phase ( 1 ~ 3 years or more ) before strong earthquake occurrence usually shows three aspects of common characteristics : for regional vertical deformation , it shows distribution features of anomalous uplift area and concentration belt - high gradient belt of vertical differential deformation ( some of them reflect distribution of four quadrants ) related to tectonics ; for horizontal movement , it shows features of centralized high strain area ( or zone ) of domination shear deformation related to active blocks and faults ; it shows common features of regional vertical deformation anomaly area and high strain distribution area of horizontal deformation 摘要强震前中期阶段（ 1 ~ 3年或稍长）区域性形变异常往往表现出3个方面的共性特徵：区域垂直运动变形呈现与构造有关的异常隆起区、垂直差异变形高梯度带（有的还呈“四象限” ）分布特徵；水准运动变形呈现与活动地块及断裂构造有关的、以剪切变形?主的高应变集中区（带）特徵；区域性垂直形变异常区与水准形变的高应变分布区共性的特徵。
The systematic analyses of light hydrocarbons show that the compositions of light hydrocarbons reveal the mixing of different genetic oils . the light and heavy components of the oils in yaha and yangtake have different sources respectively . the light components from marine formations are detected in the no . 5 and no . 7 structures in the western of yaha area 系统的轻烃研究和油源分析表明，轻烃组分更好地反映了不同成因来源的原油的混合，牙哈和羊塔克构造带原油轻重组分具有不同的来源，发现牙哈断裂构造西端5号和7号局部构造混有来自海相地层的轻组分，羊塔克构造的煤系凝析油中混有来自湖相泥岩的轻组分。
The nancha suspending - gay bridge of the changjiang road - bridge in jiangshu runyang , with a main span of 1490m , ranks first in china , third in the world . . the north rivets , only 250m from the main stream of changjiang , have a tight liaison with the waterpower of it . especially , in this area , the face of rocks undulates a lot and exist fault - fabric . the soil there has apparent difference with the trend of water . the base - hole of north rivets can be named a super - deep one , with a 60m length , 50m widths , and 48m depths . the fence of the base takes advantages of the rectangular underground continuous wall structure and succeeds 江苏润扬长江公路大桥南汊悬索桥，主跨1490m ，居中国第一，世界第三。该桥的北锚碇距长江干流仅250m ，与长江水力联系密切，锚碇区水文、地质情况复杂，表层淤泥质土及松软粘土层较厚，基岩顶面起伏较大，且存在断裂构造，土层具明显的流变特性。北锚碇基坑为长60m 、宽50m 、深48m的矩形超深基坑，其基础围护在国内首次采用矩形地下连续墙结构，并获得成功。
