A PRACTICAL METHOD FOR ESTIMATING IMPEDANCE FUNCTIONS OF BLOCK FOUNDATION RESTING ON LAYERED SOIL
-
摘要: 在地基-基础动力相互作用分析中,考虑地基分层的影响是非常重要的。虽然国内外学者在这方面已经进行了大量深入细致的研究,但是目前仅有极少一部分可应用于工程实际的简化计算方法。基于锥体模型概念,对层状半空间地基上块式基础地基阻抗函数的简化计算方法进行较为系统的研究,形成一套较完整的层状半空间地基上明置基础阻抗函数的简化计算方法。Abstract: It is important to estimate the influence of layered soil in soil-structure interaction analysis.Although a great number of investigations have been carried out on this subject,there are very few practical methods that do not require complex calculations.A simple and practical method for estimating the impedance functions of a block foundation resting on layered soil is proposed.In this method,waves propagating in the soil are traced using the conception of the cone model.
