重庆市北温泉公园后山陡崖变形破坏力学机制初探

13世纪时,温泉寺就因后山崩塌而被毁坏。1977年7月14日后山陡崖——鹤鹰岩发生崩塌,体积达3500m~3,毁坏北温泉公园附近的北碚水文站,并造成人员伤亡。近期后山陡崖变形在加剧,通过勘察,初步掌握了变形特点,本文重点讨论变形的力学机制,并建立极限平衡方程,为评价和预测崩塌灾害提供依据。

A PRIMARY RESEARCH ON MECHANICAL MECHANISM OF DEFORMED FAILURE OF STEEP BED ON THE REAR HILL IN THE NORTH HOT SPRINGS PARK, CHONGQING

As early as the thirteenth century, the Hot Springs Temple was destroyed by a rockfall on the rear hill. On July 14, 1977, a rockfall with volume of 3500m3 occurred in steep bed on the Yaoying Cliff. It destroyed the Beibei Hydrometric Station nearby the North Hot Springs Park and caused some casualties. Recently, deformation of the steep bed on the rear hill is intensifying. On the basis of the field observation, this paper makes an approach to its mechanic mechanism of de-formed failure and establishes its limiting equilibrium equation which will provide sceintific basis for evaluation and prediction about the rockfall hazard.
