嵌岩抗拔桩承载性状研究
摘要:嵌岩桩抗拔承载性状的研究目前仍较缺乏。运用灰色系统理论和非线性有限元方法,探讨了桩径、桩长、嵌岩深度对嵌岩桩抗拔承载性状的影响规律。结果表明:桩径对嵌岩桩抗拔承载力的影响最大,嵌岩深度次之,桩长最小;桩径和嵌岩深度在一定范围内与桩抗拔割线刚度呈非线性递增关系,桩长则与之呈非线性递减关系。
Abstract:There has been not enough study on anti-draw bearing properties of rock-socketed pile. The influence of pile diameter, pile length and socketed length on uplift bearing properties of rock-socketed pile is analyzed by using methods of grey system theory and non-linear finite element analysis. The results indicate that pile diameter has the strongest influence on uplift hearing capacity of rock-socketed pile, on which socketed length has much lesser influence while pile length has the weakest influence. And pile diameter and rock-socketed length shows a non-linear positive relationship with axial uplift secant stiffness of pile in certain extent, and pile length shows a non-linear negative relationship.
