Research On The Control Technology Of The Slope Disease Of Ping Xing Expressway

With the implementation of China's The Belt and Road strategy,more and more construction of mountainous expressway,the construction scale and the difficulty will increase significantly,while the slope in the construction process will produce a variety of the highway slope disaster problems have become increasingly prominent.Because of the different geological environment of the highway,the different geological problems of the highway have brought great trouble to the construction of the highway.In this paper,the engineering geological division of the high speed and the characteristics of the disease were summarized.According to Ping Xing high slope disasters are concentrated along the layer slope and coal measure strata slope typical worksite in-depth analysis,and these two kinds of slope failure mode and prevention countermeasure research,based on proposed disaster prevention design reference maps,are the main research contents and results are as follows:(1)Aiming at Ping Xing high slope disease concentrated in sedimentary rock stratum area,especially in coal bearing formation(Permian)and CIS layer of slope disaster is most prominent,of the coal bearing strata of Permian and CIS layer of slope disaster typical worksite in-depth analysis.(2)On the highway along the bed slope classification,summarizes the different types of rock slope failure mechanism;on this basis,combining with the Guangdong Ping Xing highway,on the highway along the bed slope prevention measures summarized and refined,and the preparation of the corresponding to the control reference.(3)Summary typical worksite diseases that Guangdong coal measure strata slope rock soil strength index and the coal bearing strata are classified according to the thickness of coal seam,were summarized and thick and thin slice coal measure strata slope typical slope structures and failure modes,finally,the anatomy of the typical worksite,and coal measure strata slope disaster prevention countermeasures and reference design figure is presented.
