四川红层剑门关组岩石工程地质特性研究

Study on rock engineering geological characteristics of Jianmenguan formation in Sichuan Red Bed

红层分布于世界各地,中国境内主要分布于西北、西南及华南地区,四川盆地分布最广、最连续、最典型。随着四川盆地红层地区内水能资源、水利供水与灌溉等各类工程的大力开发,红层地质特性对各类工程的兴建起了决定性作用。为了研究四川红层地质特性,本文通过对四川省南江县白垩系剑门关组各类岩石采用原位测试、物探试验及室内试验等方法,总结出了该地层各类岩石的工程地质特性,提出了后期研究建议,可为红层地区内各类工程的兴建提供有价值的参考。

Red beds are distributed all over the world,and they are mainly distributed in northwest,southwest and South China in China.Sichuan Basin is the most widely distributed,continuous and typical.With the vigorous development of various projects such as hydropower resources,water supply and irrigation in the red bed area of Sichuan Basin,the geological characteristics of the red bed play a decisive role in the construction of various projects.In order to study the geological characteristics of the red bed in Sichuan Province,this paper summarizes the engineering geological characteristics of all kinds of rocks in the Cretaceous Jianmenguan formation in Nanjiang County,Sichuan Province by using the methods of in-situ test,geophysical exploration test and indoor test,and puts forward the later research suggestions,which provides valuable reference for guiding the construction of all kinds of projects in red bed area.
