This article used rmr and q classifying method to estimate and calculate the mechanical parameters of rock in an engineering example 結(jié)合具體工程實(shí)例,用rmr及q分類(lèi)法對(duì)巖體的力學(xué)參數(shù)進(jìn)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(yīng)算法的結(jié)構(gòu)參數(shù)辨識(shí)方法來(lái)識(shí)別線性和非線性結(jié)構(gòu)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(duì)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(lèi)體系的基礎(chǔ)上合理地考慮了結(jié)構(gòu)面產(chǎn)狀及其與臨空面的組合情況對(duì)邊坡穩(wěn)定性的影響,另外將邊坡開(kāi)挖方式作為參評(píng)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(yùn)用“圍巖工程地質(zhì)分類(lèi)法” 、 bq法、 rmr法和q系統(tǒng)法進(jìn)行了地下廠區(qū)巖體質(zhì)量評(píng)價(jià);討論了四種不同方法評(píng)價(jià)結(jié)果之間的相關(guān)性。
