The Reinforcement Mechanics Of Typical Intensely Weathered Cut Slope In Southeast Of Guizhou

According to the BaiLangAo landslide of Yu-San Highway, this article discusses the reinforce methods of intensely weathered cutslope and the characters of slide and strenth, the data of soil and rock. It also evaluates the stability of the landslide, then gets an reasonable design plan to reinforce the landslide. The method that used in this article is useful to the similar landslide. The main points are briefly summarized as follows:The cut slopes deformation form, affect factors and deformation model are discassed. Then commen quantitative methods and the boundaries were introduced.The machinsm of anti-slide piles with pre-stressed anchor is analyzed. By analysis the reciprocity of prestressed anchor cable between rock and slope, the calculation methods of its interol force are dicussed.According to the BaiLangAo landslide,The regional geological environments of slope are analyzed, and physical mechanics parameters of rock are gotten. By the calculation software of LiZheng, the parameters of some typical section are got.After that,two reinforce methods are given and the economical one then to be choosed.Finally,the construetion technique and monitoring methods of anti-slide piles with pre-stressed anchor are discussed.the reinforce method is focused by full process from design to construction and monitoring.For that,the best enforce will hope to get.
