Based on summarizing harms of microartesian to construction,the authors analyzed stability of foundation under the influence of micro-artesian and confined water seepage,especially the passive earth pressure on the bracing.

The micro-confined groundwater was discovered in some parts of the Chengdu Plain.

On waterproof construction technology of basement with confined water;

Analysis of the deformation and stability of a deep foundation pit in the pumping process of the confined water inside it through finite element simulation;

Discussions on technologies of deep foundation pit projects affected by confined water;

Solid-liquid coupling study on water inrush through faults in coal mining above confined aquifer;

Mechanism study on water-inrush hazard of floor strata in mining on confined aquifer;

Based on the method of 3D similitude and numerical simulation,the variety law of aquifer of coal mining above confined aquifer is studied.

Use of specialized method for soil stabilization, freezing method, accustomed to be a rule when shaft sinking in saturated clay under high pressure water.

Based on the construction monitoring for tower part of Shanghai World Financial Centre, this paper introduces in detail the change of stress and strain of the pit, as well as, the relationship between level decreasing of the pressure water and the settlement of adjacent pipelines and constructions during excavation of the extra-deep circle foundation pit.

During the test and production of in-situ leaching of sandstone deposit, it is very difficult and complicated to exploit boreholes when confined water head of ore-bearing acquifer is quite low.

6 stiff soil-aquiclude,excavation depth and confined water head influence on deformation stability of the pit.
