摘　　要：龙口贮灰场总库容1256万m^(3),灰坝为土石混合坝,为配合北京市的绿化要求,灰场进行了增设广场、道路、亭台、管理站和植树、植草等方面的景观建设。为分析增设景观设施对贮灰场安全的影响,本文在现场调查和室内试验的基础上,通过有限元数值计算,对增设景观条件下龙口贮灰场的稳定性进行了安全分析,结果表明,景观建设后贮灰场坝体的防洪、抗滑及抗震均满足规范要求,灰坝整体安全稳定。The total storage capacity of Longkou ash storage yard is 12.56 million m^(3),and the ash dam belongs to an earth rock mixed dam.The ash yard has been built with squares,roads,pavilions,management stations,trees,grass planting,etc.in order to meet the greening requirements in Beijing.The stability of Longkou ash storage yard under the condition of adding landscape is safely analyzed through finite element numerical calculation based on field investigation and indoor test in order to analyze the influence of adding landscape facilities on the safety of ash storage yard.The results show that the flood prevention,anti-sliding and anti-seismic performance of the ash storage yard dam meet the specification requirements after the landscape construction,and the ash dam is safe and stable as a whole.
