Introduction With the development and understanding of engineering practice field deepening awareness of that structural planes such as geological fault fracture zone in the rock,soft interlayer,joints and fissures tend to become jointed dam stability and security control factor.A large number of engineering practice shows that Can directly use after dam foundation surface for the excavation to good rock mass is rarely more complex geological defects,such as faults and fissures,at this time if you continue to deepen the depth of excavation of the dam foundation,is contrary to the economic rationality of the project.Practice shows that the geological defects after some treatment measures such as consolidation grouting and curtain grouting to meet the requirements of the construction group[1][4].

Introduction Concrete and mortar, on cement based composites are the most frequently used materials in modern civil engineering.
Properties of mortar made with recycled rubber aggregate The results shown in the paper represent a part of a larger experimental research, conducted in the Laboratory for Materials at the Institute for Materials and Structures, Faculty of Civil Engineering, University of Belgrade.
Thanks to the kindness of "Tigar" corporation representatives, the Laboratory for Materials at the Faculty of Civil Engineering in Belgrade received a certain quantity of recycled tire aggregate ranging in size between 0.5 - 4.0 mm.
The usage of SCC brings engineering, economical and environmental benefits.
The so-called rubberized concrete belongs to the category of lightweight cementitious composites (density: γ < 2000 kg/m3), with possible wide-range application in civil engineering.

Prediction for long-term deformation of existing tunnels induced by underground excavation in Shanghai subway project Zhiguo Zhang1,a, Mengxi Zhang2,b and Xiao Xiao3,c 1School of Environment and Architecture, University of Shanghai for Science and Technology, Shanghai, China 2Department of Civil Engineering, Shanghai University, Shanghai, China 3Department of Civil Engineering, Shanghai University, Shanghai, China ageoyunyi2006@yahoo.com.cn, bmxzhang@shu.edu.cn, cxiaoxiao8808@163.com Keywords: tunnel engineering; underground excavation; existing tunnel; long-term deformation; 3D consolidation numerical analysis; case study Abstract.
The long-term deformation behavior for existing underground structures induced by tunneling is a hot problem which engineers designing and practicing in urban subway engineering encounter more frequently than in the past.
The engineering properties of the soils at the overlapped tunneling site are given in Table 1.
Consequently, the consolidation displacements of the existing structures should be intensively monitored in engineering practice.
