Transmission computerized tomnography among walls is used to map the surface of bedrock and the abnormal part such as karst caves and corrosion zones.

The grouting application in water outburst quick mud treatment of erosion crush belt;

Based on the investigation results obtained by shallow seismic method for the foundation of viaduct in Guangzhou,the selection of parameters for detecting karst and corrosion zone is expounded.

Electroinduced-swelling/erosion behaviors of ioncally crosslinked polyampholyte hydrogel;

Matrix erosion and water uptake were performed to elucidate the mechanisms of calcium chloride on drug release.

The swelling rate was 150% in water for injection and the 24h erosion rate was about 60% in saline.

Control of calcareous sandstone dissolution on rock mass quality in an hydroelectric station on the Jinsha River;

The speciality of gypsum dissolution of the Neogene red clay and its influence to engineering;

Repeated practices and understandings reveal that a mature gas field having been developed for 10 years is a secondary gas pool, with reservoir and seal occurring in the same strata of gypsum-dissolution cavernous-fractured argillaceous rock resulted from modern weathering and dissolution and containing gas migrating upward from the underlying gas pools and from hydrocarbon sources.
