according to the similitude law of blast and the equations of shock wave in water , this paper searched the bore wall pressure of bore water coupling charge structure and established rocky dynamical stress field under the function of blasting load ,and then obtained the crack area radius , the pulverizing area radius and the best uncoupling coefficient of bore water coupling charge in theory.

Based on exploding dynamics theory, the scope of smash area, crush area and crack area, which is shaped under the action of a blast wave and stress wave resulting from the explosion of cartridge bag, is studied .

For calculating radius of pulerizing area and crack area convenience, and conforms to engineering practice.

The research of damage characteristics of cracked rock in cold region is one of the fundamental projects in the rock mechanics research field in cold region.

Study on Elastic Modulus for Fractured Rockmass Based on Strain Coupled Hydraulic Model;

Experimental study on unsaturated seepage flow in simplified fracture model;

A numerical simulation method to determine unsaturated hydraulic parameters of fracture;

Study on cranny characteristics of the ruins of Jiaohe;

The method makes use of high frequency pulse electromagnetic wave to survey the distribution of cranny and rock solution is identified in the rocky historical relic, to provide available geologic information for the design of the rocky historical relic protection.
