考虑了岩体结构面、岩块单轴抗压强度、应力状态的影响 ,引入了 Hoek- Brown岩体经验强度准则 ,利用极限平衡原理 ,推导了嵌岩桩桩端阻力的计算公式 ;并分析了桩端阻力与桩长、嵌岩深度的关系。文中最后指出 ,尽管桩端阻力在所受荷载中所占比例不大 ,但是 ,正确估计桩端阻力对优化嵌岩桩的设计、节约造价仍有重要意义。
Considering the influence of rock mass structural plane, uniaxial compressive strength and stress state of rock mass, the Hoek-Brown rock mass empirical strength criterion is introduced, and the formula of ultimate resistance of rock-socketed pile is derived by using the principle of limit equilibrium. The relationship between pile end resistance and pile length and socketed depth. Finally, it is pointed out that although the pile end resistance does not account for a large proportion of the load, it is of great significance to correctly estimate the pile end resistance to optimize the design of rock-socketed pile and save the cost.
