Study On The Stability And Ecology Protection Engineering In High Rockmass Slope Of DianLin Expressway

Recently, With the fast development of mountain area high-grade highway construction, appeared the massive high side slopes, also has had the multitudinous high side slope distortion and the destruction, also increased the investment, also has delayed the time limit for a project, even creates had the project destruction. Because the high side slope is a geologic body part of transformation manner is a project, therefore its stable controlled in the side slope in the gneiss basic characteristic - formation lithology, the geologic structure, the rock mass structure, the slope body structure and the hydrogeological conditions and so on, as well as the artificial transformation degree - excavates highly, the slope shape and the ratio of slope.。Due to the comPlexity,diversity and non-uniformity 0f the geological conditions,slope design in road engineering can only be a practice involving Prevention as well as risk of failure.It has been shown that how to simulate the slopes'deform process,analyze the stability and make out safe and effective defending andharnessing and support measures is becoming a problem worthy of important theoretical and engineering significance.The paper take the complex rock mass high side slope ecology protection engineering research topic as the foundation, the union union road crag nature side slope characteristic value and the high steep side slope ecology protection engineering research, and the all-the-way tracking pad neighbour high speed K37+907~K38+036 side slope construction and the monitor process, unifies by the scene actual situation and the value simulation, Through the geological mechanics model and the finite element simulation, to excavates the side slope, and under the protection form side slope stress field, the bias field analysis, has promulgated under the crag nature side slope initial state and the construction operating mode condition, has confirmed the crag nature high side slope stress distribution, the distortion rule and the design achievement, and provides the basis for the protection structure and the science job practice. simultaneously through the scene home position test monitor data, further studies the crag nature high side slope the distortion rule, and to the crag nature high side slope stability around proposed the reliable basis.
