The geologic condition in mountainous district is complex variable , in different geologic , it is very difficult to find the most economically design scheme . stability of 14 high - cut slopes in guangdong province is analyzed with typical rock mass structure analysis method and stereographic projection method , and with the numerical simulation method udec this paper simulated the excavation and reinforcement courses of the important slopes . some conclutions and suggestions are based the analysis above 本文结合广东某省道沿线14个高陡岩石边坡的开挖和支护方案的选择设计,运用常用的岩体结构分析方法和赤平投影方法对边坡的稳定性进行了分析,采用udec数值模拟方法对一些重点边坡的开挖支护进行了模拟,得出了以下一些结论: 1 、边坡支护形式的选择应遵循“安全绿色、水土保持、恢复自然、环保之路”的设计原则。
On the base of foreign countries ' experiences in the expressway rock slope green design and in terms of ecological landscaping design principles , the paper set forth the basic design principles for the green design , i . e . first of all to ensure stabilized safety rock slope with engineering measures , followed by green vegetation planting of different kinds of plants , including local and naturalized plants , to be in harmony with the local landscape and capable of stabilizing the side slope , with detailed description of the key points of the design 在国外高速公路岩石边坡绿色设计经验的基础上，从生态景观角度出发，提出了宁杭高速公路东芦山岩石高边坡绿色设计以确保稳定的岩石边坡为前提然后使用多种与周围环境融洽的本地或归化植物来维护和改善生态环境的设计原则和设计内容，并详细说明了其设计要点。
The supporting mechanism of pre - stress anchor is given in following sentences in this paragraph : make full use of sectional stability , put - up steel - net shot concrete to the stratified earth as the trench is being excavated , and by this means , the little liding of soil layers and small broken slumps of rock slopes can be avoided 预应力锚板的支护机理：充分利用岩土层自身或预处理的局部的稳定性，随基坑开挖分层挂钢筋网喷射砼，以避免土层帮片及岩石边坡小的节理破碎滑塌，并把土压力传给锚板，由锚杆集中受力，通过锚杆的锚固力平衡土压力。
This paper gives detailed analysis and summary to the weathering and erosion process of rock slope , discovery the weathering velocity of rock slope is mainly controlled by such factors as lithology , structures , climate , structural characteristics of rock mass , the undulation and exposed area of rock surface , and man - made factor , furthermore , analysis the eroding mechanism of rock slope and its influencing factors 摘要对岩石边坡的风化和侵蚀过程作了较为详细的分析和总结，发现岩石边坡的风化速度主要受岩性及构造、气候、岩体结构特性、岩面起伏及其裸露程度和人为因素的控制。
