近年来,城市堆山造景工程不断涌现,但堆山堆载面积大、填筑体积大、填筑速度快,产生的沉降变形往往较大且沉降稳定时间长,特别是在软土、填土区,引发的岩土工程问题较多.堆山工程岩土工程问题中关注的重点主要为填筑堆载过程及后期的稳定、沉降及变形、工程安全影响等.文章对温榆河公园堆山工程进行坡体稳定分析,利用三维数值有限差分技术,动态仿真模拟堆载过程,综合分析堆土体变形及变化趋势,分析堆山工程对周边设施及温榆河河岸安全的可能影响,为地基处理、填筑设计与施工提供技术支撑.本研究对同类工程有借鉴意义.
Analysis and research on rock-soil engineering problems related to piled mountain in Wenyuhe Park
In recent years,urban mountain landscaping projects have emerged continuously,but due to the large loading area,large filling volume,and fast filling speed of mountain mounds,the settlement deformation caused by mountain mounds is often severe and the settlement stability time is long,especially in soft soil and fill areas,which have caused many geotechnical engineering problems.The key focus of piled mountain and geotechnical engineering issues is mainly on the process of filling and loading,as well as the stability,settlement,deformation,and engineering impact on safety in the later stage.This article conducts a slope stability analysis of the piled mountain project in Wenyuhe Park,uses three-di-mensional numerical finite difference technology to dynamically simulate the loading process,comprehensively analyzes the deformation and change trend of the embankment soil,explores the possible impact of the piled mountain project on sur-rounding facilities and the safety of the Wenyuhe River bank,providing technical support for foundation treatment,filling design,and construction,which has reference significance for similar projects.
