岩体的极限水平承载力是研究水平荷载作用下嵌岩钻井的基础。在现场试验中，由于承载能力的限制，往往无法得到极限承载力。本文采用数值试验方法，对钻孔竖井嵌岩过程进行了模拟，并对现场试验得到的荷载-位移曲线进行了扩展。本文还对常用的确定极限承载力的方法进行了分析和比较。最后，推荐了一种较为准确的确定水平受载钻孔嵌岩轴的方法。
Ultimate lateral bearing capacity of rock mass is the base of the research of laterally loaded drilled shafts socketed in rock mass. The ultimate bearing capacity is often not available because of the limitation of loading ability in field tests. Numerical tests are used here to simulate the drilled shafts socketed in rock mass and expand the load-displacement curve obtained from field tests. Common methods of determining ultimate lateral bearing capacity are also analyzed and compared here. At last, a relatively accurate method of determining laterally loaded drilled shafts socketed in rock mass is recommended.
