Introduction China is a multiple earthquake country, sudden earthquake damages seriously civil and industry buildings and causes damage of property and staff.
Soft Limiting Displacement Device Many related engineering data were investigated, especially for a few of design experiences of anti-vibration somatotype in automobile engineering and hydraulic engineering, limiting displacement device with isolation seismic was designed used material like rubber, the relationship between loads and displacement of this device under different loads is tested using test[3].

Design of Safety Monitoring System for Super-large Deep Foundation Pit in City Center Weidong Pan1,2, a, Renguo Gu1,2,b , Guixian Hu1 and Xiaolong Sheng1 1 College of Civil Engineering and Transportation, South China University of Technology,Guangzhou , 510640,China 2The State Key Laboratory of Subtropical Building Science, Guangzhou,510640,China a wdpan@scut.edu.cn, b gugool@foxmail.com Keywords: deep pit, security monitoring, remote information management Abstract:Aimed at main factors influencing the safety of super-large deep foundation pit, a safety monitoring system combined with technologies of modern compute, network, image-video transmission and GPS satellite positioning was designed in this paper.
Monitoring project and frequency of deep foundation pit.Deep foundation pit monitoring mainly focuses on stress and deformation of foundation pit, land settlement and shifting of neighboring environment[2][4] according to engineering standards such as monitoring technology standard (GB50497-2009) of foundation pit building project, engineering measurement standard(GB50026-2007),construction requirements and engineering experiences.
The system has favorable social and economic benefits which can reduce the occurrence of foundation accident by directing foundation pit construction using stress and deformation data measured on-site, and then provide practical engineering experiences for foundation pit construction in the future.

Micro-Macro characterization of granular materials Yanqiong ZHANG1, a, Xiaomin XU2, 3, 4, b and Daosheng LING2, c 1Department of Civil Engineering and Architecture, Zhejiang Industry Polytechnic College, Shaoxing, China 2Key Laboratory of Soft Soils and Geoenvironmental Engineering of MOE, Zhejiang University, Hangzhou, China 3Department of Engineering, University of Cambridge, Cambridge, UK 4Department of Civil, Environmental and Geomatic Engineering, University College London, London, UK ayanqiongz2005@126.com, bxx787@cam.ac.uk, cdsling@zju.edu.cn Key words: Granular material, Micro-scale, Coordination number, Fabric, Discrete element method Abstract: The intrinsic complexity of granular materials stems from the fact that the characterizing variables at the micro-scale and the macro-scale are of different nature.
While DEM offers numerous microscopic information at particle-scale (e.g. contact force, contact displacement, etc.), the general interests on engineering side has always been the macro-scale behaviors, generally expressed as stress and strain.
