Rock mass hydraulics is a new discipline for studying the interaction between seepage forces and stress with variable geotemperature in rock mass and effects of those coupled forces on stability of rock mass or engineering.In order to describe hydromechanical characteristic of rock mass,some basic concepts are defined. According to site investigation,the void structure of rock mass can be classified as six types,namely pore structure,sparse fracture network structure,dense fracture network structure,structure combining sparse fracture network with pore solid,structure combining dense fracture network with sparse fracture network,and structure combining fractures with conduits in karst.On the basis of hydromechanical characteristic of rock mass,the rock mass structure can be conceptualized as five types,namely quasi-pore continuum,fracture network medium,double porosity media,conduit network medium in karst,and fracture and conduit media in karst.Based on structural types of rock mass,the seepage laws of pore rock mass,fractured rock mass and conduit in karst rock mass are presented,in which the laws take into account the effects of changing stress and temperature,From practical application point view,the models of coupled stress,seepage and temperature fields in rock mass can be classified as two types,that is lumped parameter model and distributed parameter model.The former includes multi-variable auto-regression model,artificial neutral network model, and nonlinear chaos dynamical model. The latter includes continuum model, equivalent continuum model,fracture network model, double porosity media model,and generalized double porosity media model.

It was founded that a large permeable soil-body would be formed when the ant-nest system located in an air-saturated zone of dyke body had been connected with desiccation cracks and cavities, and the cement grout penetrated usually in vertical directions. The grout of awl exploration grouting began a horizontal penetration only after the vertically penetrated soil-body had become saturated. For a full well excavated down to the impervious stratum, the penetrating pattern could be considered as a model of canal...

It was founded that a large permeable soil-body would be formed when the ant-nest system located in an air-saturated zone of dyke body had been connected with desiccation cracks and cavities, and the cement grout penetrated usually in vertical directions. The grout of awl exploration grouting began a horizontal penetration only after the vertically penetrated soil-body had become saturated. For a full well excavated down to the impervious stratum, the penetrating pattern could be considered as a model of canal network according to the seepage laws of vertical flow. During managing ant risks, special precautions should be taken to the pattern of ant-nest development and rational design of awl grouting holes. A synthetic control has to be made for grouting flow and pressure, transversal horizontal displacements, opening de cracks, etc. At the same time, testing work must be well done to insure the construction quality for the purposes of eliminating ant calamities and strengthening dyke (structures.)

 位于堤身饱气带中的蚁穴系统与干缩裂缝和孔隙连通后,将形成较大范围的透水体,注入的宾汉浆液主要以竖向渗透和沿孔道流动的形式运动,只有当竖向渗透使土体达到饱和后,才会沿横向产生单向平面渗流.完整井情况下的锥探灌浆,其渗入型式可按单向渠道网络模型下的竖向渗流形式来考虑.蚁害治理工作中,必须在充分掌握蚁穴发育规律的基础上,合理设计锥孔;施工时要加强对灌浆流量、灌浆压力、横向水平位移和裂缝开展宽度等的综合控制,同时要做好质量检测工作,以确保施工质量,达到消除蚁害、加固堤坝的目的.

The river courses in the lower Heihe River are all natural ones with irregular cross sections and great seepage,belonging to broad-shallow type of sandy riverbed.The channel seepage is of great significance to ecosystems in the lower reaches which supply groundwater to sustain natural vegetation.However the seepage situation of river courses in the lower Heihe River has not been monitored and investigated for a long time.The usual percolation coefficient method thus cannot be used for calculation.At present, the amount of seepage is mostly estimated with relatively simple ways.Based on the relationship between sections and discharge,the seepage laws are analyzed according to the need of water resources real-time regulation and long series allocation.Meanwhile channel seepage laws considering the short term effects of water regime and average seepage laws of long series water resources allocation are achieved.

黑河下游河道都是天然河道,断面不规则,属宽浅型沙质河床,河道渗漏量大。下游的天然生态正是由于河道的渗漏水量补给地下水来支撑天然植被的生长,所以河道的渗漏对于下游生态意义重大。而对于黑河下游河道渗漏情况,长期以来没有系统地进行监测,利用常规的渗透系数法无法计算,目前大多是估计或者简化处理。论文根据水量实时调度和长系列水资源配置的需要,根据断面流量相关关系对其渗漏规律进行分析,分别得到了短期实时调度考虑河道前期水情状况影响下的河道渗漏规律以及长系列水资源配置情况下平均的渗漏规律。
