河北省平山县大柳树村崩塌地质灾害治理设计

崩塌与落石是山区常见的一种地质灾害，传统的治理方法多以圬工结构和钢木结构为主，这些方法存在着材料用量大、施工强度大、破坏当地原始生态环境、缺乏可靠的设计技术保障等缺点。为克服传统治理方法的缺点，本文综合考虑平山县大柳树村崩塌发育的地质环境条件，并详细分析地质灾害的发育特征后，进行设计方案比选，采用SNS柔性防护网系统对其进行治理。作者通过现场实际工程地质条件研究，确定基本计算参数和建立计算模型，计算了崩塌落石的运动能量及弹跳高度。根据计算结果，选用5m高RX-050型被动防护网，达到防灾减灾的目的。

The Designing about geological disaster of rock Fall Treatment Work in Daliushu Village of Pingshan County, Hebei Province

The rock fall is a kind of common geological disaster in the mountainous area, and the masonry structure and the steal-wood construction are traditional methods to manage the rock fall. These traditional measures have a lot of shortcomings, for instance, large amount of material, construction intensity, destroying the locality primitive ecological environment, lacking the reliable technique safeguard of designing and so on. In order to overcome the shortcomings of traditional methods, the author overall considered the geological environment condition about the rock fall development in the Daliushu Village, analyzed the developmental characteristic of geological disaster, and adopted the SNS soft protect system to resolve the problem of rock fall. The author determined the basic calculation parameters and established the computation model through the actual engineering geological condition, and calculated the movement energy and bounce height of the rock fall. According to the computed result, the author chose the passive protecting system named RX-050 which is 5m height. At last the designing achieved the purpose of disaster prevention.
