摘　　要：西部山区公路桥梁基桩往往位于陡峭岩坡上,其受力性状比平地基桩复杂。由于基桩之间的相互作用及桩与边坡的相互作用,常规的结构力学方式的计算方法显得更为繁琐而不切实际,而采用数值计算方法能考虑桩土的共同作用,计算的结果较为理想。故本文将采用数值计算法方法对双排桩进行计算,分析在施工过程中边坡及基桩的应力分布,深入探讨该类基桩受力特点,对比分析了同等条件下单桩与双排基桩桩体水平位移,具有一定的理论和工程应用价值。The bridge pile foundation always located at steep slope in western mountainous district road and its mechanics character was more complex than that in plane.Because of interaction of piles and slope,trade theory calculation method was more tedious and inapplicability and numerical calculation result was perfect because of considering the pile-soil interaction.Therefore,numerical calculation method was adopted to calculate stress of double-row piles in the paper and analyze stress distribution of pile and slope in construction process.Through the analysis,the stress characteristics of those piles were deeply discussed and horizontal displacement in pile top with single pile and double-row piles was comparative analyzed in same condition,which have some theory and engineering value.
