It also provides a reference value in the selection of subgrade materials in aeolian soil area.
Test material and method Test material.The cement in this test is Portland Cement 425, gravel, aeolianite, fly ash from local materials nearly.
Take the JH series produced by Jilin Tianyi Building Materials Company as fly ash activator.
In the lack of natural sand soil wind-blowned region, use cement, fly ash to stable wind-borned sand as pavement materials, can doing local materials, reduce the cost of projects

These interface models were initially developed to simulate composite materials, but they also became widely used in the simulation of bonded joints.
Materials.
This damaged zone then passes to form a crack that propagates across the interface until there is no longer any connection between the two materials.

Optimizing cutter's materials and structure, and the control of deformation and mass distribution can availably reduce the vibration, and depress safety decline of cutter.
Accomplishing the active control of dynamic deformation and mass distribution by collaborative design of cutter's materials and structure, makes dynamic balance precision of cutter high, the safety decline of cutter is effectively depressed, and the performance of cutter can be improved.
