【摘要】 利用自编程序ASP1.0,对滑坡的物理力学参数、桩截面型式及截面尺寸等对桩的锚深、内力、配筋量的影响进行了定量计算分析,结果表明:滑床土的内摩擦角φ对桩锚深、内力和配筋量的影响较大,桩锚深、内力和配筋量对φ变化很敏感;桩锚深、内力和配筋量对滑床土粘聚力c的变化相对不敏感;桩锚深对地基系数m的变化相对不敏感,而内力及配筋量则受m影响较大;滑坡的推力对桩的锚深、内力及配筋量影响显著,近似成线性关系,当过大的锚深导致施工困难时,单靠增大桩宽的方法来减小锚深是不经济的,而应通过调整桩距、削坡、改变桩截面等综合措施予以实现;同一滑坡条件下,空心抗滑桩一般是最经济的桩型.更多还原

【Abstract】 Quantitative analysis of susceptibility of design of slide-resistant pile to its design parameters is made with self-developed software ASP1.0.The analysis shows: the anchoring depth,internal forces and reinforcement of slide-resistant pile are in approximate direct ratio with thrust of landslide.When anchoring depth is too deep due to great thrust,comprehensive measures as adjustment of pile spacing,pile section and slope cutting are used instead of enlargement of pile width only.The anchoring depth,internal forces and reinforcement of slide-resistant pile are greatly influenced by internal friction angle φ of soil in landslide bedding and are susceptible to the variation of φ.The anchoring depth,internal forces and reinforcement of slide-resistant pile are not susceptible to variation of cohesive forces of soil in landslide bedding.The anchoring depth of slide-resistant pile is not susceptible to variation of foundation modulus m,while internal forces and reinforcement of slide-resistant pile is.Piles with annular section are the most economical among piles with rectangular section,round and annular section under the same condition.更多还原
