Heavy metal wastewater is generally of concern because of its pollution to environment and toxicity to human health [1].One of the effective means for removal of heavy metal pollutants is using adsorption materials because of their extensive microporous structure and high special surface area.
It is benefit for desorbed material to transfer again.

The mixture for the models was prepared in a common container for simultaneous grouting of all the zones in order to ensure stability of physical and mechanical properties of the material.
The model was placed in an insulated vessel to prevent material losses after the explosion.
In the course of experiments, the estimations were carried out for the average size of rock pieces from various fracture zones and linear compressive strength of the material before and after the blasting.

When modeling, 2D solid element is used to discrete concrete lining segment, soil and grouting materials.
The constitutive model of segment is isotropic linear elastic with soil and grouting material simulated with Drucker-Prager model.
The parameters of soil and grouting material of segment is listed in Table 1.

Introduction Compared with frame structure building with ordinary rectangular columns, the one with special-shaped columns not only increase usable area, but also has better techno-economic targets by using materials of light weight walls.
It would be repaired by grouting materials after the reinforcement was completed.
This phenomena may be explained as that the strengthen material and old one could not work together until several cycle running-in process passed by, so more influence of the slip can be found in the curve.
