| 摘 要： | 深入探讨了嵌岩桩的受力机制,对目前所采用的几种确定嵌岩桩嵌岩深度的方法进行了分析。针对这些方法在高强度基岩基础上确定嵌岩桩深度的不足,提出了基于桩身能力的确定方法。计算分析了各因素对嵌岩深度的影响,得到高强度基岩基础上桥梁嵌岩桩嵌岩深度的最大值。

| Abstract: | The stress mechanism of rock-socketed pile is discussed deeply and several current methods to determine the depth of rock-socketed of this pile are analyzed in this paper.Aiming at the shortages of these methods to determine the depth of rock-socketed pile on the foundation of high strength bedrock,the determination method based on pile body capacity is proposed.Different influence on the depth of rock-socketed from different factors is calculated and analyzed,and the maximum value of depth of bridge rock-socketed pile is obtained on the foundation of high strength bedrock. |
