Half - qualitative evaluation and half - quantitative evaluation , and now we adopt many traditional disposable methods to protect the slope , such as : unloading to the shelter of the landslide , propped up and block , draining off water 目前,国内外采用的斜坡稳定性评价方法虽然很多,但归纳起来不外乎是定性评价、定量评价、半定量半定性综合评价,对滑坡的防护也主要采用传统的卸载、支挡、排水等方法来进行处治。
Because each factor to affect the stability of slope takes on randomicity , the paper introduces the theory of reliability mathematics into analyzing slope ' s stability , and puts forward some formulas to calculate slope ' s reliability 摘要本文将可靠性数学的相关理论引入斜坡稳定分析中,结合斜坡在变形破坏中的各影响因素均具有一定随机性的实际情况,提出了基于概率方法的斜坡稳定性可靠性计算公式,具有一定的现实意义。
The stability of yuan edge slope is assessed and plotted out by means of the theory of fuzzy information optimization processing and research in outdoors . at last , the corresponding geo - environmental preservation - cure measurements in southern yuan of jingyang are put forward 其中,直接经济损失840 . 09万元,间接经济损失211 . 9万元;应用模糊信息优化处理方法,结合野外地质调查对塬边斜坡稳定性进行了区划,提出了相应的治理措施。
In this paper , a review of submarine slope stability studeis at home and abroad in recent years is made , and the study fields include the survey method , classification , scope and mechanism associated with the sediment failure on submarine slope as well as the submarine slope stability assessment 根据近几年来国外海底斜坡稳定性研究领域的最新成果,简要介绍分析与海底斜坡失稳有关的调查方法、分类、失稳机制、失稳空间和稳定性评价等研究情况。
Based on the study of the engineering geological conditions , using fem method to calculate the baseground stress distribution of bridge pier and analysis the stability of slope under different conditions , such as , reset condition , under the bridge load and affected by the changing reservoir water level 在对桥址区工程地质条件研究的基础上,采用有限元法方法计算了桥荷载施加前后及水库水位变动情况下桥址区斜坡应力分布特征,并对斜坡稳定性进行了分析。
Accordring to basic concept and assumes essentially on the basic of sweden method of slices , be living below the maximum equilibrium state , the function expression about stability safety homogeneous slop is deduced , and the slope surface is consist of two lines and an arc , afterwards according to analysis theory of minimal value ruling on the basic of the maximum , genetic algorithm is applied to slove the dangerousest slide situation and radius and corresponding safely factor 根据瑞典圆弧法的基本概念和基本假定,在极限平衡状态下,推导了两直线段均质斜坡稳定性安全系数函数表达式,然后根据极限分析理论的极小值原理,利用遗传算法,求出了边坡稳定性安全系数极小值,并得到最危险滑动面的滑弧半径和滑弧中心坐标。
The national highway of hurong is a backbone artery of the national west - east direction , and the traffic main artery of the development of the west regions , following the rising of our country high grade highway networked , the problem about geology of mountainous area of the highway building is becoming outstanding . so the paper puts forward the integrated control countermeasure to the slope stability , through taking the state specific geological environment of enshi area as the background , regarding the south lidu landslide as the research object , and using the method of finite element analysis 沪蓉国道是国家级东西方向的主干动脉,是西部大开发的交通要道,随着我国高等级公路网络化的兴起,山区公路建设面临的环境地质问题也日益突出。本研究论文就是以恩施州特定的地质环境为背景,以南里渡滑坡为具体研究对象,通过运用有限元分析的方法,对山体斜坡稳定性进行分析并提出综合防治对策。
This paper tells an evaluation method based on statistical analysis of geology data ? according to the history of geology change and analysis of project geology about the research section of lidu slope of hurong national highway located in south - west of hubei province , based on abundant actual investigation and experimental data , stressing on tracing the history and rules of development of slope change , we divide the data of investigation and test into two classes , one is external physical feature and structural performance , the other is factor of internal and external dynamic environment , following the analysis of mathematics statistical analysis , which points out the proportion of foundation of geology judgement and puts forward a valid identification beacon of stability 本研究内容是一种以地质数据统计分析为基础的评价方法。根据沪蓉国道南里渡滑坡研究区段的地质历史演变结合工程地质类比法,以丰富的实际勘察、试验资料为依据,以追索滑体的演化历史和发展规律为重点,将滑体的勘察、试验资料划分为外部形态与结构性状和内外动力环境因素两大类,通过数理统计分析,给出地质判据的权重,提出切实可行的稳定性判别标志。从而对斜坡稳定性提出合理的、有说服力的综合评价。
The methods of analysis and evaluation to the stability of slope , now mainl y are qualitative analysis , half quantitative analysis , physics model test and qua ntitative analysis . they all are extensively synthetically use of project geology , soil mechanics and classical mathematics physics , with the help of computers 对于斜坡稳定性的分析评价方法,目前主要有定性分析、半定量分析、物理模型试验和定量分析等,它们都是对工程地质、岩土力学以及经典数学物理通过计算机进行广泛的综合运用,各有侧重和优势。
