摘要
文章以广西桂平至来宾高速公路某800kV超高压电塔路堑边坡为例,结合其工程地质与水文地质条件,综合运用赤平极射投影、极限平衡法及Midas-Soilworks数值模拟方法对该边坡进行稳定性分析,并针对超高压电塔下复杂的场地环境,进行边坡加固防护方案研究。施工开挖与位移监测结果表明:该边坡防护方案合理可行,确保了边坡在开挖和运营中的稳定,严格控制了边坡变形,保证了超高压电塔的安全,取得了理想的边坡防护效果。
Taking a 800 kV EHV power tower cutting slope in Guangxi Gulping-Laibin Expressway as the example,and combined with its engineering geology and hydrogeological conditions,this article com- prehensively used the stereographic projection, limit equilibrium method and Midas-Soilworks numerical simulation method to carry out the stability analysis for this slope, and regarding the complex field envi- ronment under EHV power tower, the slope reinforcement and protection programs are studied.The construction excavation and displacement monitoring results showed that this slope protection program is reasonable and practicable,which ensured the slope stability during excavation and operations,and strictly controlled the slope deformation,ensured the safety of EHV power tower,and achieved the de- sired slope protection effect.
