Study on the Mechanism and the Upward-effect of Compaction Grouting;

Determination of proper position of grouting during lifting the existing subway;

Rectifying deviation and reinforcement of this unsafe building have been successfully completed by way of the diagonal bracing with anchor pile and cutting soil construction, dividingng the building into subsiding section and lifting section.

Can uplift result in abnormal high pressure in formation?;

The western Hunan and Hubei area have been considered to have nice prospects due to its lower Paleozoic is similar to that in Weiyuan gasfield,and has also experienced similar geologic process of early subsidence and intensive late uplifting in later stage.

Fission-track analysis indicates that the uplifting process of the northern segment of Altyn Tagh fault zone at the Aksay-Dangjin Pass since the Cenozoic can be divided roughly into three stages,43.
