三峡库区巴东城区岸坡稳定性问题调查研究与风险控制

Stability Investigation and Risk Control of Bank Slope in Badong Urban Area,Three Gorges Reservoir Area

巴东城区是三峡库区受地质灾害困扰最为严重的城区,通过加强地质灾害防治和风险管控体系建设,已取得连续20年保持“零伤亡”的成绩。进入后三峡时代,如何达到城区规划建设与生态环境保护协调发展是巴东县今后需面对的重大难题。针对巴东城区岸坡稳定性问题,需要有务实管用之策。研究提出应关注巴东城区岸坡整体、潜在、综合性地质安全问题,需要对西壤坡西侧岸坡实施专项整治工程,以确保巴东城区地质安全,把风险控制在允许水平。

Badong urban area is the most serious urban area affected by geological disasters in the Three Gorges Reservoir area.By strengthening the prevention and control of geological disasters and the construction of risk control system,it has achieved the goal of“zero casualties”for 20 consecutive years.In the post-Three Gorges era,how to achieve the coordinated development of Badong urban area planning and construction with ecological environment protection is a major problem facing Badong County in the future.Aiming at the problem of bank slope stability in Badong urban area,it is necessary to have a practical and practical strategy.It is proposed that attention should be paid to the overall,potential and comprehensive geological safety problems of the bank slope in Badong urban area.It is necessary to implement special rectification project on the west bank slope of Xirangpo,to ensure the geological safety of Badong urban area and control the risk at the allowable level.
