膨胀岩路堑边坡病害机理与防护技术探讨

Expansion of rock cutting slope disease mechanism and protection technology

膨胀岩因其胀缩机理、力学性状以及空间分布上的复杂性,使其成为工程地质学和岩土工程领域中最复杂的研究课题之一。该文针对工程中常遇的膨胀岩路堑边坡工程,从其病害特征出发,探讨了膨胀岩路堑边坡的破坏机理,并分析了影响因素;给出膨胀岩路堑边坡设计的基本原则,并总结了工程实践中的膨胀岩边坡防治技术措施。强调"以膨胀岩基本工程性状认识为基础,采取综合防治方法,灵活运用各类防治措施"的思想,为膨胀岩边坡工程建设提供有益的参考。

research institute co., LTD., wuhan in hubei province, 430015; 3. Henan institute of urban construction, pingdingshan, henan 467036）. Because of the complexity of rock sweling shrinkage mechanism, mechanicalproperties and the spatial distribution of expansion, make it become one of the most complicated engineering geology research topic in the field of He Yan soil engineering. Aiming at the expansion of engineeringrock slope of often encountered in the project, starting from thecharacteristics of the disease, to explore the failure mechanism of expansiverock slope, and analyzed the influence factors of expansion; given basic design principle of slope rock, and summarizes the expansive rock slopeprevention measures in engineering practice. Emphasis on “to the basic engineering properties of expansive rock known as the foundation, adopt comprehensive prevention and control method, flexible use of variousprevention measures” idea, provide a useful reference for the expansive rock slope engineering construction.
