| 摘 要： | 深入探讨了嵌岩桩的荷载传递机理,针对目前规范采用的嵌岩桩嵌岩深度计算方法的不足,根据嵌岩桩承载机理建立荷载传递方程,提出按基桩竖向荷栽传递特性确定嵌岩桩嵌岩深度的计算方法,并得到桩端荷载分担比与嵌岩深度的表达式.通过算例深入研究了嵌岩深度及桩端荷载分担比随桩顶沉降变化规律.结果表明,同等条件下桩顶沉降要求越小,所需嵌岩...

| Abstract: | Loading transfer mechanism of rock-socketed pile was deeply discussed.In view of the existing deficiency of the calculation method used in current standard for socketed length of rock-socketed pile,the load transfer equation was established according to the bearing mechanism of rock-socketed pile,the calculation method of the socketed length of rock-socketed pile was obtained based on the vertical load transfer characteristics of pile,and the expressions of pile tip load-sharing ratio and rock-socketed leng... |
