本文推广了作者及其同事发展的弹塑性连续体法，提出了一种分析嵌岩竖井水平荷载的新方法。该方法考虑了直径和/或抗弯刚度随深度变化的多层土体/岩体中的非均匀竖井。该方法不仅考虑了土体/岩体的屈服，而且还考虑了竖井因开裂而引起的抗弯刚度的降低。应用该方法对两个不同位置的嵌岩竖井进行了水平载荷试验，并与现场试验数据进行了对比分析。计算结果表明了考虑裂纹引起的轴系抗弯刚度降低的重要性，说明了该方法的简单性和可靠性。
AbstractIn this paper, a new method is proposed for analyzing laterally loaded rock-socketed shafts by extending the elastoplastic continuum method developed by the corresponding author and his colleagues. The method considers a nonuniform shaft with diameter and/or flexural rigidity changing with depth and embedded in multiple layers of soil/rock masses. The method considers not only the yielding of the soil/rock mass but also the decrease in flexural rigidity of the shaft due to cracking. The proposed method is verified by applying it to analyze instrumented laterally loaded tests on rock-socketed drilled shafts at two different sites and comparing the analysis results with field test data. The results indicate the importance of considering the decrease in flexural rigidity of the shaft due to cracking, and show the simplicity and reliability of the proposed method.
