- As a part of the project aided by nature science national fund , 《 analysis of soil - foundation - structure dynamic interaction 》 ( no . 50278033 ) , some issues about test research and simulation analysis on soil - box foundation - rc frame structure are discussed in this thesis . these issues include the development in contact modal of dynamic analysis with soil - box foundation interaction , the effect on dynamic interaction with transform in parameter both of superstructure and soil , the research on seismic isolation by changing soil stiffness and introducing research result to the seismic structure design
结合国家自然科学基金课题《地基-基础-上部结构相互作用体系动力特性研究》 ( no . 50278033 ) ,本文围绕土-箱形基础- rc框架结构动力相互作用这一课题,在前人研究成果的基础上,对动力分析中的接触模型作了新的探讨,并通过试验分析和数值计算上作了相应的研究对比;同时研究了上部结构与土的各项动力参数对动力相互作用的实际影响,并且进一步利用上述研究得出的结果,通过数值分析探讨了关于采用换土改变地基刚度而起到隔震的效果,将土-动力相互作用研究的成果引入工程抗震设计的实际工作去。 - Abstract : combining engineering practices , the main reason for concrete crack during the construction in winter of the mass concrete with box foundation floor is analyzed , the key is temperature difference between insides and outsides . some measures to prevent concrete crack from occuring is put forward . these measures feasibilities by means of temperature difference computation , concrete tension stress checking computation , temperature recordings are validated
文摘:结合工程实际分析了箱形基础底板大体积砼在冬期施工阶段产生温度裂缝的主要原因，提出了砼冬期施工的关键是防止产生温度裂缝，对防止砼产生裂缝的主要措施进行了探讨，并通过砼体内外温度差的计算，砼抗拉强度验算和测温记录验证了这些措施的可行性
