摘要
在坝基、边坡和地下洞室筹岩体工程的抗滑稳定分析中,经常遇到一个控制稳定的由多种岩性组成的滑动面,即在一个滑动面上,有坚硬完整的岩石、裂隙、软弱夹层以及其它结构面等。我们采用模拟试验和应力计算分析等方法,研究了这种滑动面的综合抗剪强度特性,最后提出了几种估算综合抗剪强度的方法及其适用性。
In the ship-resistance stability analysis of rock engineerings such as dam foundations, slops and underground cavities, we often meet a kind of slip surface which shows a variety of rock qualities and controls the stability of slip surface, i. e. on one sliding surface there are hard intact rock, fissures, weak seams and other structural planes. By the simulating test, stress analysis and calculating, we studied the comprehensive shear strength qualities of the slip surface and some methods of calculating, analyzing comprehensive shear strength. Finally, some methods of calculation and their applicability are put forword.
