Ground water is lowered by the drainage which can be caused by any deep excavation . 任何一种深的挖方都能造成排水现象从而使地下水位降低。
2.
To reduce earthwork costs, the volume of the fills should be equal to the volume of the cuts . 为了降低土方工程的费用，填方量应等于挖方量。
3.
In soft foundation strength , filling soil , excavating project it becomes more and more widely used 加筋土广泛地应用于地基加固，填方工程，挖方削坡工程等。
4.
To choice good excavating scheme , this article engages in hydraulic model tests and numerical simulation on the movable bed 为了选择较好的清挖方案，本文对太平湾电厂下游河道进行了动床水力模型试验及动床水流数值模拟研究。
5.
Because of that , engineers need to create the profiles piece by piece , and also , the data within profile drawings , such as cut - and - fill , engineers have to do it manually 此外，纵断面图的各项数据资料，如：现地高程、设计高程、挖方、填方…等资料，也必须一项一项的手动完成。

Variation of the soil suction of unsaturated soil slope under alternative action of infiltration and evaporation is studied taking a filled road slope and an excavated one as examples 将公路填方和挖方路基边坡作为典型算例，研究了入渗、蒸发交替作用下非饱和土边坡内吸力的变化。
7.
Analysis of slope stability is one of the most important problems in geotechnical engineering . the stability of all kinds of natural slope , higeway , airport , refuse dump , dam , fill , excavation need to be analysed 在土木工程中，边坡稳定分析十分重要，如各种各样的天然边坡、高速公路、机场、填埋场、土石坝工程、各种填方、挖方工程等等都需要进行稳定分析。
8.
At last , the finite element method , the strength reduction method and limit equilibrium method , nature slopes and excavation slopes , lateral stress unloading model and axial loading model are analyzed and discussed relatively 最后，就有限元法、强度折减法和极限平衡法，自然边坡与挖方边坡，围压卸荷应力路径模型分析与轴向加荷应力路径模型分析进行了比较讨论。
9.
Based all above , the digital railway plan system is developed . the system can do some operations including alternant planning the railway in the 3d terrain landscape , 3d modeling , budgeting the count of evolution , querying the information of the railway , outputting of avi 该系统实现了在三维地形景观中进行交互式的铁路选线设计，并能对设计出的铁路线进行三维建模、挖方量预算、信息查询以及三维场景的avi动画文件输出。
10.
The fresh soil and water loss caused in the road construction often appears at the roadbed , rock slope and the place for the discarded soils and gravel , which will do harm to the rivers , reservoirs and the crop fields and pollute the surrounding environment 道路建设产生的新的水土流失主要发生在挖方、填方路基、边坡、弃土(石)场以及施工过程中的乱挖、乱堆、乱倒，它主要危害建设区内的河流、水库、农田和村庄，污染周围环境。
