Study on bearing capacity of unpaved roads reinforced with coir geotextiles using finite element method (fem)

ABSTRACT

The aim of this study is to determine the ultimate bearing capacity of an unpaved road model under unsoaked and soaked conditions by using finite element method (FEM). The numerical methodology applied in this investigation to know the ultimate bearing capacity is subjected to vertical load, to apply the application of finite element method (FEM) using ABACUS software. The results reveal the variation in the magnitude of the stresses, displacement pattern and in bearing capacity by inclusion of untreated and treated coir geotextiles under unsoaked and soaked conditions. However, further validation of the results presented in this paper is recommended using an experimental study conducted on similar size unpaved road model. The proposed study can be useful for the Civil Engineering where a good quality rural road network is required.

摘要

本研究的目的是使用有限元法 (FEM) 确定未铺砌道路模型在未浸水和浸水条件下的极限承载力. 本次调查中采用的数值方法用于了解垂直荷载作用下的极限承载力, 以及使用ABACUS软件应用有限元法(FEM) . 结果揭示了未经处理和处理的椰壳土工布在未浸泡和浸泡条件下的应力大小、位移模式和承载力的变化. 然而,建议使用在类似大小的未铺砌道路模型上进行的试验研究,进一步验证本文中给出的结果. 建议的研究可用于需要高质量农村公路网的土木工程.
