【摘要】：目前，國(guó)內(nèi)外對(duì)于滑坡的預(yù)測(cè)預(yù)報(bào)研究大都是針對(duì)整體高邊坡的，而對(duì)于露天礦臺(tái)階邊坡，以及公路、鐵路路基邊坡等僅有十幾米高度的臺(tái)階規(guī)模邊坡研究甚少。此類(lèi)邊坡滑坡時(shí)主要是由節(jié)理面控制的楔形體滑坡，雖然規(guī)模不大，但卻是經(jīng)常發(fā)生的現(xiàn)象，它比整體邊坡的滑動(dòng)更經(jīng)常性的影響生產(chǎn)。 本文對(duì)滑坡的預(yù)測(cè)預(yù)報(bào)主要是基于臺(tái)階邊坡的楔形體進(jìn)行研究，通過(guò)對(duì)白云鄂博鐵礦主礦即將開(kāi)挖形成臺(tái)階邊坡的區(qū)域，進(jìn)行地質(zhì)信息采集、節(jié)理裂隙等的采樣試驗(yàn)工作，在此基礎(chǔ)上，運(yùn)用概率論與統(tǒng)計(jì)、理論分析、計(jì)算機(jī)編程等進(jìn)行研究。本文主要研究?jī)?nèi)容有：（1）對(duì)現(xiàn)場(chǎng)實(shí)測(cè)節(jié)理面數(shù)據(jù)進(jìn)行統(tǒng)計(jì)分析，得出其概率分布及特征值。（2）采用蒙特卡洛模擬原理，在[0,1]區(qū)間內(nèi)產(chǎn)生服從各自概率分布的的均勻隨機(jī)數(shù)，在長(zhǎng)方體框內(nèi)模擬出與實(shí)測(cè)邊坡在統(tǒng)計(jì)學(xué)上大致相同的巖體結(jié)構(gòu)模型，并編制了相應(yīng)的模擬程序。（3）將臺(tái)階邊坡的尺寸與等效節(jié)理巖體模型相互匹配，形成具有臺(tái)階形狀的節(jié)理面網(wǎng)絡(luò)模擬圖。根據(jù)邊坡面上各個(gè)節(jié)理面出露線的交叉及組合情況，利用空間解析幾何、塊體理論和赤平投影的方法，找出邊坡面上可能組合形成的楔形體。（4）依次選取臺(tái)階邊坡上每一個(gè)可能組合成的楔體，抽樣產(chǎn)生其節(jié)理面的強(qiáng)度數(shù)據(jù)，，計(jì)算該楔體的體積及滑坡概率。對(duì)找出的所有的楔形體都進(jìn)行這樣的計(jì)算，即可預(yù)測(cè)出臺(tái)階邊坡各個(gè)部位發(fā)生滑坡的概率。 本文研究成果是對(duì)即將開(kāi)挖形成的臺(tái)階邊坡的滑坡概率分布情況進(jìn)行預(yù)測(cè)預(yù)報(bào)，有助于邊坡工程師們?cè)谠O(shè)計(jì)中及時(shí)采取有針對(duì)性的預(yù)防措施，避免滑坡隱患，降低滑坡后再修改設(shè)計(jì)造成經(jīng)濟(jì)損失。
[Abstract]:At present, most of the researches on landslide prediction and prediction are aimed at the whole high slope, but there is little research on the bench slope of opencast mine and the slope of highway and railway roadbed with a height of only 10 meters. This kind of slope landslide is mainly wedge-shaped landslide controlled by joint surface, although the scale is not large, but it is a frequent phenomenon, it affects the production more frequently than the whole slope slide. In this paper, the prediction and prediction of landslide is mainly based on the wedge-shaped body of the step slope. Through the sampling test work of geological information collection and joint fissures in the area where the main mine of Bayan Obo Iron Mine is about to be excavated to form the step slope, On this basis, the use of probability and statistics, theoretical analysis, computer programming, and so on. The main contents of this paper are as follows: (1) the statistical analysis of the field measured joint surface data is carried out, and the probability distribution and eigenvalue are obtained. (2) the Monte Carlo simulation principle is used to generate uniform random numbers from their respective probability distributions in the [0 ~ 1] region. In the cuboid frame, the rock mass structure model which is statistically similar to the measured slope is simulated, and the corresponding simulation program is worked out. (3) the dimension of the step slope is matched with the equivalent jointed rock mass model. A network simulation diagram of joint surface with step shape is formed. According to the intersection and combination of the exposed lines of each joint on the slope surface, the spatial analytic geometry, block theory and the method of stereographic projection are used. Find out the wedge formed by the possible combination on the slope surface. (4) select each possible combination wedge on the step slope in turn, sample the strength data of the joint surface, calculate the volume of the wedge and the landslide probability. The probability of landslide in every part of step slope can be predicted by calculating all the wedges. The research result of this paper is to predict the landslide probability distribution of the step slope which is about to be excavated, which will help the slope engineers to take timely preventive measures in order to avoid the hidden danger of the landslide. Reduce the landslide and modify the design resulting in economic losses.
