An Experimental Comparison of Compressive Strengths of Soils Stabilized with Enzyme and Ground Quicklime Hongtao Peng1, a, Haitao Su2,b , Xinping Zhang 1,c , Jun Wang1 1College of Water Conservancy and Civil Engineering, CAU, Beijing 100083, China 2Glodon Software Co., Ltd, Beijing 100193, China apwb@cau.edu.cn, bshtcau@126.com, czhangxinping@cau.edu.cn Keywords: Compressive strength, Enzyme, Ground quicklime, Soil.
Lime product such as ground quicklime, is used in large quantity as building and engineering material.
Methods The ground quicklime was often added to soil at a ratio of 3:7 (v:v) in many civil engineering projects in China[6].
The ratio of Perma-Zyme : soil is at 1:33000(v:v) , as used for some civil engineering projects in China.

Studies on seismic performance test of Precast prestressing shear wall Rirong Fu1,a, Zhichun Liu1, Qilin Yin2, Kun Su2 1Shandong Jianzhu University, School of Civil Engineering, China Shandong Jinan 250101 2Shandong Jianzhu University Architecture and Urban Planning Design Institute 250013 afurirong@163.com Keywords: precast prestressing shearwall;axial compression ratio;effective prestress;seismic performance;finite element analysis.
(3)The effective prestress are 0.4fptk,0.5fptk,0.6fptk in this paper,we could see from the result,when we increase stretching control stress within certain range,bearing capacity of the structure would increase,but ductility decrease,so we use 0.5fptk as the effective prestress at practical engineering.
