One of the critical factors concerning dam construction on the water-saturation soft soil foundation is the seepage consolidation process.

To determine the parameters needed in this model, the consolidation constitutive relationship of high plastic soft clay and other fine-grained soil, the seepage-induced consolidation test and analysis were provided.

This paper introduces the research Status at home and abroad, the main model, disaster-cause of land subsidence and land subsidence overview in Xi\'an, especially the xi\'an land subsidence mechanism test, that is the test of xi\'an land subsidence physical model and the test of infiltration and consolidation under high-pressure.

Preliminary discussion on penetration depth of cementitious capillary crystalline waterproofing material;

Application of cementitious capillary crystalline waterproofing materials in concrete segments of subway;

Microscopic analysis and study on performance of cementitious capillary crystalline waterproofing agents;

The impermeability and compressive strength of samples treated by permeable crystalline coating for different coverage rates and curing time were investigated.

In order to study the performance of YJH permeable crystalline coating and its effect on the microstructure of concrete the impermeability and self-healing ability of samples treated by YJH permeable crystalline coating for different coverage rate and curing time was investigated.
