南水北调中线小三峡特大桥桥位区地质评价

Engineering geology evaluation of the location of Xiaosanxia super large bridge in middle-line construction of south-to-north water transfer project

结合工程实例,介绍了桥位区的工程地质条件及岩土物理力学性质,通过对推荐线与比较线桥位区进行的工程地质评价比选,得出推荐线更为经济合理。

Combined with practical work enginee.ring geological conditions and mechanieal properties of rocks in the site of bridge are introduced. Engineering geology evaluation is made for alternative selection of location of bridge between recommended line and comparative line. Comparison show recommended line is more suitable.
