堤防

In chapter 4, by analyzing the interchange of seepage water between overburden layer of weak permeability and sandy gravel bed, a short computer program for adopting weighting soil layer on the landside of dike is put forward, the optimal design schemes about combination weighting soil layer with inverted drainage works are studied.

第四章 通过分析堤基弱透水覆盖层与下卧砂砾层之间的渗流关系，创建了堤防背水侧盖重压渗的快捷计算模型并研制了相应的计算软件，提出了盖重压渗与反滤导渗相结合的优化设计方案。

The levee being worked on in front of my house!

堤防正在进行这项工作，在前面我的房子！

The determination of probability distribution of seepage parameters is a basis of reliability analysis of levee seepage stability.

确定渗透参数的概率分布是堤防渗透稳定可靠性分析的基础。

The model can be used in earth-rock allocation of mad engineering and levee engineering widely.

优化模型可以广泛应用于道路、堤防等工程的土石方调配问题中。

Risks caused by many uncertainty factors in levee engineering are cared about by people.

堤防工程中因各种不确定性因素引起的风险正日益受到人们的关注。

Seepage deformation and other problems related with seepage are the main cause of danger in levee during the flood period.

渗透变形以及与渗透有关的问题是造成堤防在洪水期间险情的主要原因。

Thus, each overflow serves to build the channel levee up a little higher.

因此，每个溢流，以建设渠道堤防了一个高一点。

GIS technology has been put into use in the field of landslide analysis, soil and water conservation, and levee construction monitoring.

阐述了GIS技术在长江流域岩土工程中的部分应用状况，主要是分析三峡地区滑坡、堤防监测和水土保持相关领域工程应用情况。

Based on the flood level frequency curve, hydrological failure risk was divided into flood overflowing risk and flood overtopping risk.

基于推求的洪水位频率曲线，将堤防水文失事风险分为洪水漫溢风险和洪水漫顶风险。

The current approach is based on a design water level corresponding to the return period for overtopping of the dikes, which is increased with a safety board of at least 0.5 m TAW 1985; MTPWWM 2005a; Van der Most et al.

目前的办法是基于一个设计水位相应的回报期overtopping的堤防，这是增加了一个安全的董事会至少有0.5米（托策1985年； mtpwwm；的Van der大多数等人2005年）。
