Analysis and discussion were made on the influence to blasting construction in mud-filled fracture according to the experience of blasting construction in Jiangyunding tunnel,and the countermeasures were also put forward.

Discussion on the formation mechanism of silted tensile cracks in a hydropower station dam area in southwest China;

Based on this , the forming mechanism of the water-filmed siltized intercalation and release of residual structural stress are explained, and then the main treatment of drainage is proposed.

The stability of rock slope engineering is generally controlled by rock structure,especially the mudded intercalation,so it is needed to control the main rock structure in slope for the purpose of stability improvement.

Residual strength prediction of siltized intercalations by support vector machine;

The dynamic triaxial shear test on the dynamic properties of the Xiaolangdi in situ siltized intercalations within core samples is performed.
