Debouch bar microfacies and frontal sheet sand microfacies are considered as the most favorable facies belts for sandstone reservoir distribution and development.

提出水下分流河道微相、河口坝微相以及前缘席状砂微相是砂岩储层分布和发育的最有利相带。

The Tertiary reservoir in the vertical orientation develops three high porosity zones, every one firstly occurs in the sandstone of debouch bar and braided-divided flow channel, secondly occurs in the sandstone of raised bank and channel bar.

第三系储层在纵向上发育三个高孔带，各高孔带主要发育在沉积微相为河口坝、辫状分流河道的砂体中，其次发育在天然堤和心滩的砂体中。

Past investigation found the rock in the right dam foundation composing of granite(γ_4~3～γ_5~1) in dyas- trias,which has a very complicated mechanical environment. The complicated phenomenon is as follows: tectonism, alteration, rock mass demobilize, rock mass stress release and other factors.

前期的调查表明其右岸岩体力学环境复杂，表现为：构成右岸坝基岩体主体的二迭～三迭纪花岗岩(γ_4~3～γ_5~1)受构造变动、蚀变、风化卸荷等因素的影响形成了坝基软弱岩带和坝肩上部卸荷松弛岩体。

The interpretation of a typical sub-bottom profile reveals that the diapir of the Yellow River delta resulted from the interior deformation of soft prodelta layers at the delta front.

高分辨率黄河三角洲典型的地震地层和解释地层剖面、浅地层剖面和钻孔资料联合解释表明，海底刺穿的发源层来自于河口沙坝下部的前三角洲相软弱层变形。

The Es2-3 Member with buried depth more than 3500m in Banqiao-Beidagang area, consists of clastic rocks, develops a sedimentary system mainly containing deep-water turbidite fan,fan delta and alluvial digitate sand bar.

板桥—北大港地区深层（3500m以下深度）沙二段、沙三段发育以深水浊积扇、扇三角洲和冲积扇指状砂坝为主的碎屑岩沉积体系。

Soil's dispersibility is the important element to determine whether it is suitable for the engineering and to evaluate an index of dam's stability.

土料的分散性是决定土料能否用于工程的重要因素，也是土坝稳定性评价的一项重要指标。

According to synthesize evaluate, the distributary channel sandbodies and river mouth bars are best reservoir.

通过综合评价认为，水下分流河道和河口砂坝微相为本区最好的储集层。

Within the four types of flow units, type A has perfect reservoir property and distributes in lower part of distributary channds.

研究结果表明，在4类流动单元中，A类具有最好的储集物性，主要存在于分流河道下部；B类储集物性较好，主要存在于分流河道和河口坝中；C类储集物性一般；D类储集物性最差。

This paper analyses the distributive law of axial compression in concrete wall and its influnce on strength of reinforced concrete penstock with steel lining located on the downstream surface of a concrete dam by the finite element method and model tests with material similar to prototype.

通过几个电站的有限元计算和仿真材料模型试验成果，分析混凝土坝下游面钢衬钢筋混凝土管道的轴向应力分布规律及其对管壁应力的影响，可作为管壁三维强度分析的依据，并指出在轴向压力和内水压力作用时裂缝更早发生。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
