  1. ( 2 ) because of t he variability of rock subjected to outside action, three new conceptions : postive damage basic damage and negative damage, are suggested, which can deal with the condition that rock density became large. ( 3 ) the present damage variables based on ct number mostly include ct average number of the rock without damage, which is difficult to measure, so a new damage variable, which includes the average ct number is proposed, on the other hand, strain equal theory is generalized because the one put foreword by lemaitre is not good enough to use. ( 4 ) a axial damage constitutive equation is proposed and testified. ( 5 ) with the circle times, the damage propagation laws of two different rocks, subjected to circle of freezing and thawing, are studied, and in the analysis process, traditional analysis method including average ct number and is used, some important conclusions are reached : inner damage of soft rock containing a large mount of apertures is largely propagating with the time increasement of circle, however, at the preliminary time, the hard rock containing a small mount of aperture is a little propagating, at late time, the influence become large ; ( 6 ) zone separation and statistics frequency put forward is used to analysized the three different damage propagation in the open circumstance, when they are subjected to the different circle times of freezing and thawing, in which the temperature variability is linear, different freezing rate, and different freezing temperature, and no water is supplied during the test

    在研究過程中本文主要做了以下工作： （ 1 ）針對巖石損傷變化較小時，運用ct均值和方差分析不方便的缺陷，本文提出運用對ct數范圍劃分區段的方法，根據各區段統計頻率的變化規律來分析損傷擴展狀況； （ 2 ）針對巖石受到外部作用的多變性，本文提出了基準損傷，正損傷，負損傷的概念，在某種程度上考慮了巖石受到外部作用時的壓密情況； （ 3 ）現有的基於ct數的損傷變量大多需要用到巖石基體的ct均值，這實際上是很難觀測到的，因此本文建議了一個可運用巖石初始狀態ct均值的損傷變量，由於現有的勒邁特教授應變等價原理使用上的不便，本文在其基礎上進行了推廣； （ 4 ）建議了一個可用巖石初始狀態ct數和彈性模量的單軸損傷本構方程，並用算例進行了驗證； （ 5 ）對兩種不同巖石在開放環境下受到凍融循環作用且融化過程中補水時，內部損傷隨凍融循環次數增加的擴展規律進行了探討，主要運用了常規的ct均值和ct方差的分析方法進行分析，試驗發現：對于孔隙率和含水率較高，密度和強度較低的軟弱巖石，凍融循環次數對損傷結構的擴展有明顯的影響，而對于孔隙率和含水率較低，密度和強度較高的硬巖，凍融循環次數對其損傷結構擴展初期由於含水率低的原因，影響不是太大，而後期由於水補給后，含水率較高的原因，凍融影響逐漸增大； （ 6 ）運用了本文提出的區段劃分和統計頻率的方法，深入地分析了開放環境下的線性溫度變化的凍融循環次數，凍結溫度，凍結速度不同巖石作用時，其內部損傷隨凍融循環次數，凍結速度和凍結溫度變化的擴展規律，需要指出的是除了在試驗前飽水外，凍融過程中沒有補水。
  2. Based on five years regional water - salt monitoring data and related hydrological and weather information in the smaller scale experiment zone ( shahaoqu ), the regional water - soil ( salt ) environment regime including grounder water table depth, water quality, superficial layer ( 0 - 40cm ) and middle layer ( 40 - 70cm ) soil moisture and saline concentration are simulated, tested and predicted using bp model. at the same time, the rbf model is be used to calibrate the results of bp

    以一個小尺度試驗區的多年區域水鹽監測資料及水文氣象資料為建模依據，對試區非凍期（作物生長期）的地下水位、地下水質、土壤水鹽（ o - 40cm ， 40 - 70cm ）的水-土（鹽）環境狀況進行了較為深入全面的模擬預測，並進行了rbf模型預測結果的對比。
  3. 4. the study on the frozen soil feature and its influence on the runfall of the catchment in qilian mountains. the results indicated that the soil begins to freeze around october 20, and finishes melting around august 20 of next year. altitude slope side, vegetation condition of the land and temperature are the factors influencing the depth and the time of soil

    4對祁連山區凍土特徵及其對流域徑流的影響研究表明，祁連山林區土壤每年的10月20日左右開始凍結，較低海拔的到第二年的8月20日左右消融結束；海拔、坡向、植被、下墊面狀況、溫度是影響凍土深度、早晚的制約因素；凍土厚度與徑流量成反比關系。
