强夯地基处理振动效应的研究
摘要:强夯法是地基处理的重要方法之一,在进行强夯地基处理时要评价强夯振动效应,评价的基础正是强夯振动振幅和振动衰减规律。以昌平区沙岭新村工程场地为例,通过对回填场地进行强夯振动监测,分析了强夯振动最大振幅及其随距离的衰减规律,并用频率的四次多项式表示场地介质衰减指数。在场地介质作用谱和强夯激励谱的基础上,通过计算得到介质作用函数和强夯激励函数。通过不断积累强夯振动效应资料,建立起不同性质岩土体与场地介质作用函数之间的关系,进而明确工程岩土体的物理力学性质和动力学表现之间本构关系。
Abstract:The method of dynamic compaction is one of important methods for ground treatment, the dynamic compaction to evaluation of dynamic compaction vibration effect, the basis of the evaluation are dynamic. This article takes the Changping District ridge village site as an example, through the landfill site for dynamic compaction vibration monitoring, analysd the dynamic compaction vibration amplitude and attenuation law of frequency, and the four polynomial representation field medium attenuation index. In field medium action spectra and dynamic excitation spectra based on, obtained by calculating the dielectric function and dynamic excitation function. Through the continuous accumulation of dynamic compaction vibration data, set up different properties of rock and soil and ground medium function relationship, then clearly engineering rock soil physical and mechanical properties and the dynamic performance between constitutive relation.
