摘要
近来,在建筑工程的许多不同方面都越来越普遍地使用连桩。要确定施加在连续桩上的剪力和力矩值,需要进行大量的分析和计算,尤其是在遇到地震时。本文介绍了用于计算该值的 ANN 数学模型,该模型结合了 144 个输入集,分别代表挖掘高度(H)、H 与嵌入深度之比(D)、保留土壤的单位重量( )和内摩擦角( )。所获得的数学模型显示了可接受的回归和偏差。研究发现,桩身受到的剪力和弯矩值随着( )的减小而减小,随着( )的增大而增大。挖掘高度(H)是影响模型输出值的最重要输入参数。
Estimating Max moment and shear exerted on contiguous piles subjected to earthquake using ANN.
Recently the usage of Contiguous piles in many different aspects of construction projects are become more common. Determination of the shear force and moment values exerted on the contiguous piles require extensive analysis and calculations especially when earthquake is to be encountered. ANN mathematical models for calculating this value combining 144 input sets that represent height of excavated (H), ratio of H to the depth of embedment (D), unit weight of retained soil ( ) and angle of internal friction ( ) is presented in this paper. The mathematical models obtained show acceptable regression and deviation. It was found that both shear and moment values subjected on the piles are decreases with the decrease of ( ) and increases with the increase of ( ). The height of excavation (H) was found as the most important input parameter that affects the output values of the models
