中文摘要: |
赤水市丹霞地貌作为世界自然遗产地及国家地质公园,拥有着全国面积最大和最具典型代表的丹霞地貌资源。研究发现作为赤水市典型景观的丹霞地貌,一直因风化剥蚀和重力崩塌作用而发生不同程度的破坏。本文从岩体温度应力效应和差异性风化两方面进行定量定性分析赤水丹霞地貌受损机制,经计算,温度应力效应导致赤水嘉定群砂岩岩体产生的剥落主要发生在岩体立面0.12 m范围内;差异风化形成倒岩腔,会发生倾倒破坏景观。 |
英文摘要: |
It is found that as the typical landscape of Chishui municipality,Danxia landform is always damaged at different level by weathering erosion and gravity collapse effectThe paper makes a quantitative and qualitative analyze of the danxia landform’s damage mechanism on the aspect of rock body temperature stress effect and differentiating weatheringIt is calculated the peel off of chishui Jiading group sandstone rock caused by temperature stress effect mainly occurs on the range within 012 mThe differentiating weathering causes the rock gravity,which will tilt to break landscape. |
