摘要
随着国家西部大开发战略的推进,高原铁路设计逐渐成为当前重要的研究课题。高原铁路设计不仅需要考虑陡峭的地形条件和地震动等不利因素,还需兼顾严格的位移控制要求,常规的陡坡路基设计方案已不能满足设计需求。鉴于实际工程需要和某高原铁路陡坡路基设计的复杂性,基于TRIZ理论分析设计参数间的相互关系,采用技术矛盾矩阵的方法获得陡坡路基的设计方案,并采用有限差分软件FLAC3D对设计方案进行了验证。结果表明,基于TRIZ理论得到的设计方案在一般工况和地震工况下均能满足设计要求,基于TRIZ理论的高原铁路陡坡路基方案设计是可行的。
With the advancement of the national strategy for the development of the western region,the design of plateau railways has gradually become an important research topic.The design of plateau railways needs to consider not only steep terrain and factors such as seismic activity but also strict requirements for displacement control.Conventional design solutions for steep slope subgrade are no longer able to meet the design requirements.Considering the practical engineering needs and the complexity of designing a steep slope subgrade for a certain plateau railway,this study analyzed the relationships between design parameters based on TRIZ theory and obtained the design solution for the steep slope subgrade using the method of technical contradiction matrix.The design solution was validated using finite difference software FLAC3D.The results show that the design solution obtained based on TRIZ theory can meet the design requirements under normal working conditions and seismic conditions.Therefore,the plateau railway steep slope subgrade design based on TRIZ theory is feasible.
