摘要
通过对岩石变形特性及其破坏机理的深入分析 ,对岩溶区桥梁桩基桩端持力岩层安全厚度的确定进行了较全面的探讨 ,提出了一系列便于工程应用 ,且经济、安全可靠的计算公式 ,并结合湖南省潭邵高速公路建设 ,对公式的使用范围、注意事项。
According to a deep analysis to rock deformation characteristics and its failure mechanism, a thorough discussion about determining the safety thickness is made in this paper. A series of conveniently applicable, economical, safe and reliable equations is proposed for the safety thickness of the bearing rock strata at the ends of piles in karst region. And in conjunction with the construction of Tan Shao Expressway in Hunan Province, the discussion about application scope, attention items, influence factors of the equation and selection of reasonable safety coefficients are made.
