Experimental Study on the Axial Compressive Strength and Elastic Modulus of GHPFRCC Li Xiuling1,a, Wang Juan1,b 1School of Civil Engineering, Shandong Jianzhu University, Jinan, China, 250101 adlutiem@163.com, bmswangjuan@163.com Keywords: green high-performance fiber-reinforced cementitious composites (GHPFRCC); axial compressive strength; elastic modulus; the ability of deformation; energy consumption Abstract.
How to improve the mechanical behavior of concrete is becoming the hot problem in the engineering field.
With the development of the micromechanics and fracture mechanics, the engineering cementitious composites (ECC) has been increasingly popular in the world [1-2].
The results show that the mechanical property of GHPFRCC is different from concrete, and GHPFRCC has a promising prospect in the aseismic engineering field.

The Establishment of the Peat Soil Curing Model with Unconfined Compressive Strength Jingwei Wang1, a, Wen Pan2, b, Zhuoyin Jiang3,c Faculty of Civil and Architectural Engineering, Kunming University of Science and Technology Kunming, Yunnan, 650500, China a304693863@qq.com, b502854199@qq.com, c419171180@qq.com Keywords: Curing agent, the unconfined compressive strength, strength model Abstract: This article discussed the applicability of the curing agent, the growth and change of the peat soil curing unconfined compressive strength and under the different variables (such as cement, curing agent formula, construction waste, age).
Introduction The influence rule of the mixed curing agent has just been established, in order to configured dosage of curing conforms to the desired engineering, and can be easily seized and used by engineers.
But there are also many factors such as soil sample moisture content, soil void ratio, stress history of soil, soil structure, curing agent of water cement ratio, outdoor temperature, soil organic matter content of the sample which could be having an influence on the figures in engineering. the establishment of the stabilized soil strength prediction model of mathematical relationship should be followed: (1) yis for the strength of solidified soil type, xi is for the factors influencing the content.

Introduction In engineering design and analysis of slope stability, a lot of models are bring used.
Consequently, model outputs on which engineering design and analysis are based are also uncertain, and should be represented as random variables.
Many problems related to stability of environmental engineering are best approached using uncertainty and reliability methods.
