Examples
- Road beds for high performance roads
道路的稳固 - However , the effect of blast quake and blast feedback often affect the stability of mountain slope and steep road bed deeply . they may induce disasters such as toppling . slipping and debris flow , also , they affect the safety and economy of engineering
然而，爆破震动效应及其连锁反应对山坡体或高陡路基的稳定性具有很大影响，很可能诱发山坡体的崩塌、滑坡甚至泥石流等灾害，严重影响工程的安全性和经济性。 - Because the finite element method consider the relation of stress - strain of rock soil , so , it is more accurate and rational than other methods that it calculates side slope stability coefficient . the paper takes the road bed landslide as an synthetical protect system to the prevention of the slope , through the analysis of the origin cause of formation and stability analysis of different position , and adopting different methods to carry on rational and effective protection after studying different positions , in order to put forward the synthetical protection system
由于有限元计算方法考虑了岩土的应力? ?应变关系，因此，其求解的边坡稳定系数比其它方法更为精确合理。而对于滑坡的防治本文则采取了路基?滑体综合防护体系，通过对滑坡成因的分析及不同部位的稳定性分析，研究了不同位置采用不同的方法进行合理有效的防治，以求形成综合防护体系。 - ( 2 ) study on the mechanics mechanism of the calamity caused by the cave of the highway : based on the investigation in detail along the line of the highway in shan - gan loess plateau , the distribution law , the classification and characteristic of hazard of highway cave are presented ; the calamity mechanism of highway cave opposite side slope and road bed is discussed , especially the mechanism of collapsing of the hidden cave in road bed . propose " the effect of hidden corrosion " , etc . 10 kinds send to mechanism of collapsing . based on the principle of limit balance , the formula of the critical treating thickness of hidden cave is put forward as follows : according to different stratum , different size and depth , the calculation of the critical thickness of the hidden cave of roadbed has been carried on
( 2 )公路洞穴的致灾力学机理研究：在对陕甘黄土高原区公路沿线黄土洞穴详细调查基础上，研究了公路洞穴分布规律、危害分类及致灾特点；公路洞穴对边坡及路基的致灾机理，重点是路基暗穴致塌机理，并提出了“潜蚀效应”等十种致塌机制；利用极限平衡原理导出路基暗穴临界处理厚度计算公式如下：针对不同地区不同地层，对不同尺寸和埋深的暗穴，进行了路基暗穴临界处理厚度的计算。 - Particularly four following respect problems of main research of this thesis : first , excavating and optimizing of the road bed and the slope protect , on the basis of influence factor analysis and the slope design principle by the expressway of mountain area of limestone , we excavate the model of optimizing after putting forward the road bed which is suitable for the expressway of mountain area of limestone , through employ this optimize model , we can reduce the amount of road bed excavate , thus maximum reducing slope excavate destruction to environment and pollute ; according to limestone mountain area expressway characteristic of the cutting slope , we use the law of finite element and rmr of revision carry on stability analyze and appraise to their side slope ; combine the limestone rock body characteristic of mountain area , we have analyzed the corresponding side slope safeguard procedures
论文主要研究了以下四方面问题:第一,路基开挖优化。在分析石灰岩山区环境特征的基础上,探讨了石灰岩山区路线设计的原则与方法;在应用有限元数值分析方法对边坡的开挖稳定性进行分析的基础上,提出了陡开挖强支护的石灰岩山区高速公路的路基开挖方式,并建立了填挖平衡,开挖面积最小的石灰岩山区高速公路的路基开挖量优化模型;结合石灰岩山区岩体特性,探讨分析了相应的边坡防护措施。第二,土石方处理及自然水系调治恢复。
