摘　　要：现场调查发现:古人在建造北响堂寺石窟 3 号窟时,至少运用了 3 点符合现代科学原理的方法和技术,其中包括效果良好的选址、洞窟斜墙“设计”和排水系统等。这对现代工程地质和岩石力学研究的发展具有一定借鉴作用。笔者从工程地质和岩石力学角度对其上述工程科学亮点进行了详细论述,对于斜墙“设计”的论证是借助于 Flac-3D 三维数值计算进行的。通过对斜墙开挖下石窟围岩关键部位的拉应力分布情况、剪应力的大小以及变形等的分析,表明斜墙“设计”可使围岩的应力条件得到多方面的改善,有利于石窟的稳定。According to the field survey of No.3 grotto of Beixiangtang Temple, the highlights of ancient grotto engineering technique are found unexpectedly in many respects, including good site selection, design of inclined wall and drainage system etc.. All of these present the ancestral intellectuals and may be used for references at modern research of engineering geology and rock mechanics. The above scientific highlights are discussed in terms of engineering geology and rock mechanics. Using the three-dimensional numerical computation by Flac-3D software, the tensile stress and shear stress distribution are analyzed at the key part of the surrounding part of the inclined wall. The results of calculation analyses indicate that the design of the inclined wall improves the stress condition of the surrounding rock, thus in favor of the stability of the whole grotto.
