Main creative points of the thesis are as following:1. It is the first time to apply 2-D and 3-D turbulent model of the air-water two phases flow to the study on hydraulic properties of groyne. It makes description of the turbulent flow field to be possible precisely. This offers a more accurate method to determine the water surface in channel improvement.2. Based on the results of experiment and simulation for 3-D turbulent model of air-water two phases flow, a new formula to compute the height of damming is built.3. Based on the 2-D mode and the formula to compute the height of damming, the subdivision method of 2-D computation for water surface at upstream and downstream.

认为泥质砂岩的导电体积由两部分组成，即完全被束缚水占据的微孔隙(孔喉半径小于 0 。1μm ，其中的流体不能渗流)导电体积和有效孔隙中被可动水、束缚水占据部分的导电体积，泥质砂岩的整个导电响应为二者之和，但二者导电体的导电特性不同，各有其不同的几何因子。

The effect of Reynolds number on rudder hydrodynamic performance is also analyzed. Up to the stall angle the computed lift and drag agree well with measurements and other author's calculations, whereas stall angle, lift and drag beyond the stall angle are slightly under-predicted. The solver is used to investigate laminar and turbulent separated flows around a 6: 1 prolate spheroid at high incidence angles and their effects on hydrodynamic forces. The second separation flows are successfully identified in both laminar and turbulent flow simulations.

The results show that the development and dissipation of dynamic pore water pressure are coinstantaneous,which makes the plus and minus pore water pressure and seepage force both alternate with time.

动孔隙水压力随车速的增大而增大，而且由于水压力的存在路面弯沉和面层内的有效应力减小了，但水对沥青膜的乳化和置换作用加强了。

In order to analyze the influence and damage of the top and bottom of rock mass in floor water-resisting layers due to water pressure in water bearing layer and mining pressure, this paper applies the methods of similar material simulation test and mechanical analysis of floor water invasion in the near of faultage to further comprehend the mechanism of floor water invasion.

为了分析底板含水层水压及采动矿压对底板隔水层岩体上部与下部的影响与破坏，应用了相似材料模拟试验以及断层附近底板突水的力学分析方法，对底板突水机理有了进一步的认识；同时，由断层附近底板突水的力学分析方法所得到的理论计算结果，也可以作为判别类似条件下遇断层时承压水体上采煤是否安全的依据。

I have me my summer vacation in a town last year.since whose are there.some of my relations,there have a good view for the mountain and river,I think it's a great place be to rest,one day when i ride my bike on the small path,this river catch my eye for very clearly but like very deeply,becauese i can't see the end of the water,then.some chap shouting make me look at,they catch a a short boy and thow he in the water with a heavily,waiting for a moment yet the boy not up the water,i'm very worry and jumping in the river,i want float out but some watergrass be enteine my leg and the body is deeper at every movey,i don't know past how long time,i feeling one small hand help me break up the watergrass and push me to the surface of the rive,after that i just kown they are hvae a playing who can sit in the swim and make a long time in deep water,but i want cry for the joking,becauese i couldn't swim but i have a forget.

去年我在一个小镇上度暑假，因为那里有我的亲戚，我认为那里有好山好水是一个静休的好地方。一天当我在小路上骑着自行车时，一条非常清澈但好像也挺深的小河吸引了我的视线，因为我好像看不到河的底端，这时，一些小孩的叫喊声因起了我的注意，他们抓住一个矮小的小男孩然后重重的扔进了水里，待了一小会这个男孩没有露出水面，我非常担心就跳进了水里，我想浮出来，但一些水草缠住我了的腿，我每动一动身体就会越往下沉，我不知道过了多常时间，我感觉有一双小手帮我弄掉腿上的水草并往水面推着我的身体，后来我才知道他们是在玩看谁在水底呆的时间长的游戏比赛，但我对于着样的笑话想哭因为我忘记自己了不会游泳。
