现浇薄壁管桩成桩振动影响研究
|
摘要
介绍现浇薄壁管桩成桩振动的特点和评价方法.为合理评价现浇混凝土薄壁管桩技术的沉桩振动效应,结合一现浇薄壁管桩软基处理工程,进行成桩振动对周围环境影响的实测分析.分析结果表明,现有评价方法存在不足,指出今后应加强不同场地成桩振动传播规律和建筑物安全振动强度阈值的研究.
An introduction was given to the characteristics and evaluation method of vibration during piling of cast-in-place thin-wall concrete piles.In combination with a soft ground project,which was improved by cast-in-place thin-wall pipe piles,the influence of vibration during piling was analyzed,and the method for reasonable evaluation of the vibration effect of piling of cast-in-place thin-wall pipe piles was discussed.The result shows that the method currently used is imperfect,and it is suggested that the research on the regularity of vibration propagation at different sites and the shreshold value of vibration strength to ensure the safety of buildings should be strengthened in further study.
