摘要: 介绍了一种山区道路拓宽技术——整体式悬挑结构,运用有限元软件数值模拟了岩土对荷载的响应,提出了 其简化计算方法;用visual C++编写了一种适用于该结构的计算程序,对该结构与岩土的共同作用进行了研究;得 出了不同土体对结构受力的影响,实际工程选用老填土和碎石土是经济的。

关键词: 悬挑与土体, 共同作用, visual C++

Abstract: A new structure of widening mountain road with integral cantilever(ICS)is introduced.In order to analyze the response of rock.soil to load.numerical simulation is done by making use of the finite software;and then a simplified calcu- lation method is brought forward.Furthermore.a calculation program is compiled by visual C++,which is suitable for this strueture.Finallv.the interaction between integral cantilever structure and rock-soil is researched by using the calculation Drogram.The resuhs show that the structure stress is affected by diferent soil;it is economic to choose old landfill and grav- el soil in practical engineering.

Key words: integral cantilever structure and rock-soil, interaction, visual C++
