Research on Stability Analysis and Support Measure of High Slope of Traffic Artery in Industrial Park
The slope of 2#road in an industrial park in Yunnan is up to 41 m,which is dominated by soil slope,and the slope toe is mainly silty clay.The slope has a large risk of instability in the rainy season,which seriously threatens the construction safety.For this reason,this paper proposes to use pile,anchor and anchor rod frame support in the sections with high and steep slope,and use lattice beam+anchor rod support for the slope in other sections.The diameter and spacing of the rotary drilling piles are 1.4 m and 2.0 m respectively.The horizontal prestress of the anchor cable is 100-300 kN,and the vertical spacing between each anchor cable is 2.0 m.After adopting the proposed support scheme,the road slope did not lose stability during the construction period,indicating the reliability of the support scheme.
