小硐室爆破在湘中紫色页岩生态建设中的应用研究

Application of Little Cavity Blasting in Purple Shale Ecology Construction of Central Hunan Province

在衡阳地区紫色页岩分布较广,由于历史原因,生态环境受到破坏,水土流失严重。为了尽快恢复生态结构,开发紫色页岩的经济前景、进行景观地貌改造、建设与利用,文中采用爆破小硐室方法,在紫色岩中产生深1.8 m、直径1.6 m左右的圆柱形坑体。通过水土保持、土体改良等措施,并优选出树(草)种,加快湘中紫色页岩的生态建设。与此同时,通过特殊爆破与山体造型,结合自然景观的特色进行人工景观的设计与造型,加快湘中紫色页岩景观建设。

Purple shale is distributed widely in the Hengyang region. Because of historical causes, ecology of the region has been destroyed and rail has been lost seriously. In order to renew the structure of ecology, to exploit the economic perspective of the shale, to transform the scenery and topography and to utilize the shale, some 1.8-metre-depth and 1.6-metre-diameter cavities were created using the blasting method. Then, through conserving soil ,rod water, improving roil and choosing suitable trees and grasses, ecology of the shale may be constructed rapidly in central Hunan Province. In the mean time, by special blasting, shaping the mountains and designing the manmade scenery with natural scenery combined, scenery of the shale may be constructed rapidly.
