They are always used as foundation to support load in civil engineering or construction materials, benefit to mankind.
Constitutive relationships and strength are needed in geotechnical engineering prediction and design.
With the development of hardware of computer and software engineering, now a number of open sources based on DEM, like Yade[3], ESyS-particle[4] and LIGGGHTS[5] etc., have provided researchers platforms in investigating behavior of granular materials.
In some cases of geotechnical engineering, granular materials suffer erosion under the interaction of water.

Study and application on cutting technology of underground drifting blasting Xiantang Zhanga, Peng Zoub, Hongmin Zhouc, Hongli Wangd Shandong Provincial Key Laboratory of Civil Engineering Disaster Prevention and Mitigation, Shandong University of Science and Technology, Qingdao, Shandong 266590, China azzxhtm@163.com, bkdzoup@163.com, chongminzhou@163.com, dskdwhl@163.com Key Words: Drifting, Blasting parameter, Cutting； Abstract: Because of the weak borehole sealing and inadequate use of the initial free face, the higher investment and unsatisfactory blasting effect still exist in the mine tunnel excavation blasting.
For tunneling problems and similar coal mine engineering experience[2],in the fine-grained sandstone takes two cutting programs as shown in Table 1,Table 2,Part I program for closed small empty holes spiral cutting; Part II program uses linear cutting shown in Figure 1.
In engineering we arrange in accordance with the relevant empirical data.
