基于Geo-slope软件的码头陆域顺层岩质高边坡分级加固计算

Gradual reinforcement calculation of bedded rock high slope in wharf land area based on Geo-slope software

针对山区河流码头陆域开挖形成高30~50 m顺层岩质边坡的加固处理问题,根据加固设计方案中格构锚索和抗滑桩的排间距,采用Geo-slope软件,在摩根斯坦-普拉斯法的基础上,建立顺层岩质高边坡加固计算模型,计算多组不同排间距不同工况下的边坡稳定安全系数,从而选定经济安全的边坡加固组合方案。结果表明,格构锚索与抗滑桩加固对边坡整体安全系数的影响大小取决于支护结构在整个滑面上产生抗力的大小。

Aiming at the problem that the mountainous rivers terminal land excavation forms 30 m to 50 m high bedded rock slope reinforcement,according to the lattice anchor and anti-slide pile in the reinforcement design of row spacing,we use the Geo-slope software,establish the high bedded rock slope reinforcement calculation model based on the Morgan Stanley-Plath method,calculate the multiple sets of different row spacing of slope stability safety coefficient under the different working conditions,and select slope reinforcement combination of economic security.The results show that lattice anchor cable anchor and anti-slide pile reinforcement effect on the overall safety factor of slope depends on the size of the supporting structure in the whole slip surface resistance.
