As for this, for tunneling projects with complicated geological conditions, engineers have to adopt combined approaches and technologies to comprehensively predict geological condition for the tunneling project according to the practical situation in the disaster area, conducting all-sided analysis, utilizing the advantages of different approaches and to achieve the best prediction effect[1~3].
Advanced Prediction of Comprehensive Geological Condition Firstly, engineering and hydro-geological information of the construction area shall be comprehensively analyzed to fully recognize the geological condition of the tunneling area, to explicit the distribution of soluble rock, structural development, surface drainage, lowest erosion basis, subsurface stream, as well as weak, fracture, water-bearing stratum, fault fracture zone and other special geological zones, so as to figure out the prediction focal point and to formulate the prediction plan.
By contrast, based on macro geological analysis and short-distance prospecting, comprehensive geological prediction technology provides engineers with all-sided and three-dimensional information about the geological body distribution in front of the tunneling face.

Water jet vacuum dust suppression device used to tunnel development Jian Liu1, a, Na He1 ,Yinwen Wu1 and Jin Liu1 1 Civil and Environmental Engineering School, University of Science and Technology Beijing, Beijing 100083, China aanyonell@126.com Keywords: tunnel development, water jet and vacuum dust suppression, heading face Abstract.
Since the reform and opening up, tunnel and underground engineering developed rapidly in china.
To this end, the majority of researchers and field engineers and technicians, a lot of theoretical research and testing, research and exploration of high-pressure spray, water curtain dust, ventilation and dust, filter dust and other dust measures, however, there are some inadequacies in the implementation process.
Expressed in the parameters of the jet characteristics, but the most common continuous water jet engineering applications, people are most concerned about is the basic parameters, namely, a jet of hydrostatic pressure (referred to as the jet pressure), the jet flow, velocity, and power recoil kinetic parameters and structural parameters of the initial segment of the jet length, jet width.

Damage Effective Functions Described Based on Combination of Macro and Micro Damage Mechanics Zhanhong Qiu 1, a, Wohua Zhang 2,b and Helong Chen1, c 1 Architectural and Civil Engineering College, Taizhou University, Taizhou, China 2 Geotechnical Engineering Institute, Zhejiang University, Hangzhou, China aqiuzhanhong@126.com, bzhangwohua@163.com, chlchen1131 @tzc.edu.cn Keywords: Isotropic elastic damage; Damage effective functions; Damage evolution equation; relation of porosity and damage.
In practice, however, the most of engineering materials are micro-fractured.
In order to express the kinetic behaviors of porosity and permeability, a material property evolution model has to be developed for investigation of damage growth behaviors of engineering materials.
Whereas if the damage variable Ω is directly considered (defined) to be the porosity Φ, when applying Ω=Φ and employing the relationship between Lame’s constants λ, μ and engineering elastic modulus E, v, the analytical formulations of these two damage effective functions Ψλ(Ω) and Ψμ(Ω) for the 2-D random distributed circular micro-voids can be obtained based on Eq.(18) and Eq.(19) as , (26) Eq.(26) is actually obtained under the assumption that Ω=Φ.In fact the natural definition of damage is carried out by area deduction rate as Ω=(A-A*)/A, but the porosity is physically defined by a volumetric deduction rate as Φ=(V-V*)/V.
