摘要
为了使理论结果能尽可能准确地反应实际情况,就土质地基上受多个集中力作用的有限长梁的内力计算方法进行了对比分析。采用基于W inkler假定的计算方法和基于弹性半无限空间理论的计算方法,通过理论分析这两种计算方法的差异,并采用FLAC3D进行数值模拟。计算结果表明基于W inkler假定的计算方法较真实地反应了有限长梁的实际受力情况。
For making the theoretic results close to the fact, two methods used to calculate the internal force of beams with finite length bearing several point loads and on soil foundation were compared. These two methods were based on the Winkler＇s assumption and the half - space elastic foundation theory respectively. Through theoretic analysis, the difference between the two methods was found. And with the aid of FLAC^3D analysis, it was clear that the results deduced by the method based on the Winkler＇s assumption were more close to the fact.
