震区滑坡应急治理技术——以四川省理县林业局后山滑坡为例

Emergency treatment technology for slope in seismic area

依托四川省理县林业局后山滑坡工程,在应急勘查水文、地质等环境的基础上,开展了滑坡体稳定性计算,提出了"裂缝封填+排水沟+抗滑桩+片石挡土墙"的综合治理方案,有效防止了依托工程产生大规模变形。此外,为确保其整体稳定性,对各单项工程进行了优化和细化设计,保障了受威胁区人民的生命财产安全的同时,也为类似滑坡治理工程施工提供技术依据。

Relying on the slope engineering project behind the forestry bureau of Li country in Sichuan Province, the slope stability calallation was developed on the basis of the emergency hydrographic survey and geological en- vironment. Meanwhile, the comprehersive treatment plan, i. e. ＂fissure filling together with drainage ditch and an-ti - slide piles as well as rubble retaining wall＂ ,was put forward, which prevents the slope engineering from large deformation effectively. Moreover, in order to ensure the whole slope stability, the optimal and refined design for
