| 摘 要： | 岩体自重和剥蚀作用都是形成岩体初始应力场的重要因素。在地应力回归分析中，反演所得岩体重度往往大于实测重度。通过算例说明，地表剥蚀作用因素是导致该结果的主要原因，并分析了由此产生的一些工程应用问题。

| Abstract: | The gravity of rock masses and denudation are important factors in the construction of initial stress field. The unit weight got by the conventional back analysis is usually larger than that obtained by the test in-situ. An example is studied to show that such phenomenon results from the earth's surface denudation. Based on the result,some engineering practical problems are explored. |
