江郎山一线天岩壁风化落石分析与防治

Analysis and Prevention of Weathered Rockfall on Jianglang Wall in Jianglang Mountain

指出了江郎山以郎峰、亚峰、灵峰三神峰而闻名于世,被中外游客称为"神州丹霞第一峰"。通过现场多次实地考察、测量,收集第一手素材,根据区域地质背景、地层、岩性、构造及风化作用等方面对江郎山丹霞地貌的成因作了分析,并对江郎山一线天两侧岩壁风化落石情况进行了现场量测,根据量测结果可知:落石下落的速度可达78.99 m/s,冲量最大49.08N·s,相当于近30倍的56式步枪杀伤无防护人体产生的杀伤力,危害非常巨大。对此,专门提出了一些技术方面的创新,采用柔性拦石网防护技术,既最大程度提高了安全系数,又保护了原始的生态地貌。

Jianglang Mountain is famous for its three holy peaks of Lang Feng, Yafeng and Lingfeng. It is called “the first peak of Shenzhou Danxia” by Chinese and foreign tourists. Through many on . the . spot investigations and measurements. first. hand materials were collected.The causes of Danxia landform in Jianglang Mountain were analyzed according to the regional geological background, strata, lithology, structure and weathering.And on. the. spot measurements were carried out on the weathered rock fall on the rock walls on both sides of the first . line sky in Jianglang Mountain. According to the measurement results, the falling speed of rock fall can reach 78.99 m/sand the maximum impulse is 49.08N·s, which is equivalent to nearly 30 times of the 56 . type rifle killing the unprotected human body with harmful damage. In this regard, some technical innovations were carried out using flexible stone net protection technology, which not only maximizes the safety factor but also protects the original ecological landform.
