For Goupitan Hydropwer Station on Wujiang River,over 1 200 anti-uplift anchor pile s are arranged in the water cushion pool to anchor the non-uniform soft rock strata composed of shale,clay rock,silty clay rock,thin layer of marlite and less medium-fine calcareous sandstones etc.

乌江构皮滩水电站水垫塘部位布置了1200多根抗浮锚桩，对页岩、粘土岩、粉砂质粘土岩，及夹薄层泥灰岩和少量中细粒钙质砂岩等不均质软岩层软岩进行锚固，原设计锚桩的间距为2.2m，为了优化设计，缩短工期，在施工前进行了4根锚桩原位抗拔试验，根据锚桩在抗拔过程中周边一定范围内岩体变形沿径向的分布规律，及破坏时裂隙的扩展形态和范围，确定了锚桩的间距，在此基础上提出了锚桩间距的优化方案，并应用于工程施工。

The result indicates that Chang 6^2 is a delta-lacustrine depositional system, and the principal producing pay is in subaqueous distributary channel where deposit fine sandstones and have good physical properties. The areas in the center of subaqueous distributary channel get high oil-produce while the flanks gel lower oil-produce relatively. The distribution of oil layer is mainly controlled by lithology, and Chang 6^2 is lithologic reservoir developed in the monocline setting which clime to the northwest.

研究表明：长6^2储层为三角洲－湖泊沉积体系，主要产油层位于长6(上标 2-2)的水下分流河道中，沉积细砂岩且物性较好，河道中心地区的产油量相对较高，而河道侧翼地区的产油量相时较低：长6^2中的油层分布主要受岩性控制，是在北西倾料的单料背景上发育的岩性油藏。

Through S-wave polarization scanning mode of ultrasonic impulse testing, rock samples with three different properties are measured to evaluate the variation of S-wave velocity in three perpendicular coordinates. By analyzing S-wave splitting of three directions and polarization of the maximum or minimum speed S-wave amplitudes, we think that the velocity orthotropy and fracture orientation observed in the grain sandstones and crack marble samples can be estimated in terms of the polarization and velocity of S-wave. Also, perpendicularity characteristics on the two types of rocks can attribute to the bedding and structure of rocks (directional grains or crystallize).

在实验室通过选择了三种不同岩性的岩石，采用超声脉冲测试方法中的横波偏振扫描方式，观测了岩石样品三个坐标方向上的横波速度变化，通过分析三个传播方向上出现横波分裂的差异，以及出现最大或最小快慢横波振幅的偏振方向发现，可从横波偏振方向和速度值判断出纹理砂岩和裂隙大理岩样品存在不同程度的速度正交各向异性和裂隙方向等特征，认为这两种岩石的正交特性的原因是岩石的层理或裂隙与岩石本身的结构构成的。

The predicted sand bodies are distributed in north-cast and approximately north-south orientation. The sandstone reservoir, which is getting thin and pinch out to the high west-north structure, is easy to form the lithological trap with sand body updip pitchout and the structural lithologic trap. Lens sandstones developed and are distributed in source rocks, It is easy to form lithologic traps.

预测砂体分布呈现出北东向、近南北向展布特征；向西北构造高部位方向变薄尖灭的储集砂体极易形成上倾尖灭岩性圈闭及构造－岩性圈闭，透镜体砂岩也较发育，其分布于生油岩区，容易形成岩性圈闭。
