Comparative Analysis of Several Common Quasi-statics Methods for Tunnel Seismic Soil Pressure Calculation Tongfa Deng1,a , Yong Gui1, b, Fusheng Nie 2,c 1Jiangxi University of Science & Technology, GanZhou,Jingxi 341000,China 2Communications Design Institute of J.X.
In view of the biggest drawback that the quasi-static method for the calculation of seismic soil pressure is failed to reflect dynamic properties of loading and materials, as well as dynamic reaction of constructure-soil system, specialized dynamic analysis should be carried out in case of large seismic acceleration instead of determination tunnel seismic soil pressure briefly through simplification of certain retaining structure.

This wide band gap material has superior electrical and thermal properties over silicon which makes it a better candidate for high power high temperature applications.
Al2O3 is one of the dielectrics that can be used as an etching mask which has the advantage of high material density (3.95~4.1g/cm3) compared to tetraethyl orthosilicate (TEOS~0.93g/cm3) deposited with LPCVD method, hence it is more resistive to dry etching.
