This article used rmr and q classifying method to estimate and calculate the mechanical parameters of rock in an engineering example 結合具體工程實例,用rmr及q分類法對巖體的力學參數(shù)進行了估算。
In this thesis , a parametric identification method for non - linear hysteretic systems is presented based on recursive model reference ( rmr ) adaptive algorithm 本文采用了一種基于模型參考自適應算法的結構參數(shù)辨識方法來識別線性和非線性結構的系統(tǒng)參數(shù)。
And the plasticity of height , crown amplitude , leaves morphology , leaf number , allocation of biomass ( including : lmr , rmr and shoot / root ratio ) and lar were low to soil water for all three species . 5 而株高、冠幅、葉片形態(tài)、葉片數(shù)目、生物量在器官間的分配(包括: lmr 、 rmr和根冠比)和lar對土壤水分的可塑性均較小。
In smr system , the relation between discontinuities and slope freeing face was considered , so was excavating method . however , slope height was omitted in this system . as a result , smr is 5 - 10 point lower than that of actual stability Smr法在rmr分類體系的基礎上合理地考慮了結構面產(chǎn)狀及其與臨空面的組合情況對邊坡穩(wěn)定性的影響,另外將邊坡開挖方式作為參評因子,較全面地考慮了各種影響因素的綜合作用。
( 2 ) the rock mass quality was assessed based on the data obtained from exploration adits with the methods of engineering geological classification for surrounding rock mass , bq , rmr and q - system successively . and th en the correlations between the assessment results of different methods were discussed 基于勘探平硐獲取的資料,運用“圍巖工程地質(zhì)分類法” 、 bq法、 rmr法和q系統(tǒng)法進行了地下廠區(qū)巖體質(zhì)量評價;討論了四種不同方法評價結果之間的相關性。
Research shows that four factors have great influence on the formation of complex rock mass . first , rock mass subjected six times of tectonic movement during long period of geo - history , each tectonic movement produced fractures and associated joints corresponding to the orientation of maximum principal stress and deteriorated the properties of fractures formed at former period ( s ) . second , down - cutting of langcangjiang river produced unloading fractures 采用了四種巖體質(zhì)量分級評價方案對研究區(qū)巖體質(zhì)量進行了研究,這四種方案包括:工程巖體分級標準( gb50218 - 94 ) 、水利水電圍巖工程地質(zhì)分類( gb50267 ? 99 ) 、巖體rmr分類( bieniawski , 1973 ) 、巖體質(zhì)量指數(shù)z分級(小灣, 1995 ) 。
2 . all the corresponding parameters of a . sylvestris were similar with c . smyrnioides in procreate period in april . but the parameters of root length , diameter of root , volume of root , leaf biomass , root biomass , total biomass , root mass ratio ( rmr ) and sla had the maximal value in moderate treatment in vegetative period in january 峨?yún)⒌南鄳L參數(shù)在4月生殖生長期與明黨參隨土壤水分的變化趨勢相似;但在1月份的營養(yǎng)生長期,根長、根粗、根體積、葉生物量、根生物量、總生物量、 rmr和sla均以中度水分條件最大。
By means of qualitative and quantitative analyses , such as geologic anslysis , the classifying of slopes stability staging hierarchy - q , rmr , smr , csmr , the classifying of the newly put forward from the subject staging hierarchy - hsmr which is adapted to classify the slopes of highways in southwest mountain areas , stability calculation 通過地質(zhì)分析、已有邊坡穩(wěn)定性分級體系q 、 rmr 、 smr 、 csmr分級、結合課題研究提出的適合西南山區(qū)公路分級的新系統(tǒng)? ? hsmr體系分級,穩(wěn)定性計算等定性和定量的手段,評價了廣渝路華鄰段13處邊坡的穩(wěn)定性現(xiàn)狀及發(fā)展趨勢。
After long - term synthetic action of these factors , the complicated rock mass in the right dam foundation come into being . the adjoining rock engineering geological classification of water - conservancy and hydraulic - power project reconnaissance code ( gb50287 - 99 ) , geomechanic system ( bieniawski , 1973 ) , rock mass quality index z ( xiaowang , 1995 ) , artificial neural network and field classification were used in the rock mass quality classification 本文采用水利水電工程地質(zhì)勘察規(guī)范( gb50287 - 99 )的圍巖工程地質(zhì)分類、巖體rmr分類( bieniawski , 1973 ) 、巖體質(zhì)量指數(shù)z分級(小灣, 1995 )以及人工神經(jīng)網(wǎng)絡分類,對壩區(qū)巖體按其基本指標作出定量化評分、分級。
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 論文主要研究了以下四方面問題:第一,路基開挖優(yōu)化。在分析石灰?guī)r山區(qū)環(huán)境特征的基礎上,探討了石灰?guī)r山區(qū)路線設計的原則與方法;在應用有限元數(shù)值分析方法對邊坡的開挖穩(wěn)定性進行分析的基礎上,提出了陡開挖強支護的石灰?guī)r山區(qū)高速公路的路基開挖方式,并建立了填挖平衡,開挖面積最小的石灰?guī)r山區(qū)高速公路的路基開挖量優(yōu)化模型;結合石灰?guī)r山區(qū)巖體特性,探討分析了相應的邊坡防護措施。第二,土石方處理及自然水系調(diào)治恢復。
