柔性框架石笼在大型崩塌体治理工程中的应用——以5·12汶川地震区豆芽坪崩塌错落体为例
|
摘要
5.12汶川大地震诱发了许多大型崩塌体,对这类崩塌体尤其是处于江河强势冲刷下的大型崩塌体,采用常规的治理工程措施显然是很不适宜的!柔性框架石笼就是针对都汶路最突出的豆芽坪崩塌错落体提出的一种新型防护工程。这种防护工程不仅便于就地取材,经济实用,而且较好地解决了依然处于变形调整中的崩塌体工程治理问题,突出了柔性防护的特色,具有一定的应用和推广价值。
5·12 Wenchuan Earthquake induced many large-scale rock collapses.For such collapses,especially forcefully eroded by river,conventional controlling measures are clearly no longer feasible.Flexible Stone-gabion Framework is a new type of protective works designed to control the most prominent Douyaping Collapse on Duwen Road.This protective works not only facilitates the use of the local materials,economically and practicably,but also solves the problem of collapse controlling still in deforming.In conclusion,the Flexible Stone-gabion Framework highlights the characteristics of flexible protection and deserves applicating and popularizing in some extent.
