采动影响下公路损害特征及防护

Damage features of highway affected bymiming and protections

应用弹性力学和岩层与地表移动理论 ,在实地调研的基础上 ,分析研究了公路受采动损害的现象特征及原因 ,给出了公路受采动损害的判据 ,并提出了减轻或预防公路采动损害的技术措施。对预防或处理公路受采动损害问题具有一定的理论和实践意义 ,同时丰富和发展了采动损害研究的理论和实践。

By applying the theories of elasticmechanics and the theories of movements of and ground surface,on the basis of field investigation and studying,the damage features of highway affected bymiming has been analyzed and studied in this paper.In the meantime,the judging method of highway damage affected by mining and the technical measures of preventing highway from damaging have been raised.It is considered that the theory and practice of studying on the damage affected bymining have been developed and enriched.
