通过对盐镇至潼关间隧道区的黄土进行物理力学试验研究,得出其物理力学指标并分析其物理指标与力学特性的关系及影响,重点指出各物理力学指标对黄土湿陷性的影响,进而指出其对黄土区工程建设可能带来的危害和影响,提出相应的工程处理措施,对黄土区的工程建设等具有一定的指导和借鉴意义。 Through the physical and mechanical tests on the loess in the tunnel area from Yanzhen to Tongguan, the physical and mechanical indexes of the loess were obtained, and the relationship between the physical and mechanical properties was analyzed. The influence of various physical and mechanical indexes on the collapsibility of loess was pointed out. Then it points out the harm and influence it may have on the engineering construction of the Loess Plateau, puts forward the corresponding engineering treatment measures, and has some guidance and reference significance to the engineering construction of the Loess Plateau.
