摘要介紹了大孔隙及大孔隙流的定義、多種表現形式及其重要特徵、產生機理和室內外實驗研究概況,以及染色示蹤、切片、穿透曲線、張力入滲儀、 x射線ct掃描攝像和雷達探測等方法的研究進展,揭示這些實驗方法的優點與存在的問題。Elastic - plastic analysis for soil around anchor jacked pile in this paper, the course of penetration is regarded as expansion of cylindrical cavity in infinite soil mass. combining with the knowledge of elastic mechanics and plastic mechanics, we can make analysis for soil around pile. finally, we can educe the cylindrical cavity pressure, radius of plastic zone, radical displacement in elastic zone, excess pore water pressure in soil around pile and spherical cavity pressure at the end of pile
錨桿靜壓樁樁周土體的彈塑性分析該部分是文章的主要工作所在,本文把壓樁過程樁周土體的本構關系看作是水平面的平面應變小孔擴張問題,利用小孔擴張原理,結合彈性力學以及塑性力學的知識,對壓樁後土體的性狀作出分析,得出樁對土的擠擴作用力、樁周土體塑性半徑、彈性區的位移,壓樁完成瞬時樁周土體彈性區和塑性區的超孔隙水壓力以及樁端球形孔擴張的擴張力。Some numerical technicalities, such as choice of fundamental solution to governing equation of flow problem, treatment process to corner point problems, automatic meshing, treatment process for fractures partly beyond the flow domain boundaries, were also discussed. thirdly, a hybrid bem - channel model was presented, and the numerical procedure for which was described
進行了裂隙巖體的多孔介質水力等效性分析,研究了裂隙巖體的滲透系數的張量形式,闡述了裂隙巖體等效水力性質的計算方法,包括rev大小的估計和等效滲透系數張量的計算。According to thorough research on mechanical mechanism of 3 - d tensional micro - fracture producing, this point is put forward the first time that : there is more stress concentration in the circumference of micro - cracks. and the cracks are easier to expand and to link with each other when the fissures contained saturated pore fluid than dry state. therefore, it is necessary to modify the griffith criteria
4深入研究了三維張性微裂縫形成的力學機理,首次指出:在裂隙內飽含孔隙水的情況下,微裂縫周邊的應力集中程度更高,裂縫更容易擴展乃至連通,因此,在張裂縫發育的研究中應該對格里菲斯準則進行修正。Along with increase of pressure, the parameters such as velocity, amplitude, main frequency and quality factor of seismic wave change big gradually, while change very weakly with the change of temperature. through testing research for artificial crack and pore model, we conclude that crack density, azimuth, opening and the change of pore have obvious influences on speed, amplitude, attenuation ( or quality factor ) and main frequency of seismic wave etc. but, seismic wave dynamic characteristics are more evident than its kinematical characteristics for the change of crack and pore parameters. therefore, it offers reliable experiment foundation for detecting crack and pore by seismic wave kinematical characteristics ( such as amplitude, attenuation and main frequency etc. )
通過對人工裂縫和孔洞模型的超聲波實驗研究,可以認為:裂縫密度、方位、張開度和孔洞密度的變化對縱橫波的速度、振幅、衰減(或品質因子q )和主頻率等參數均有明顯的影響,但裂隙參數的變化對地震波動力學特徵參數(振幅、衰減、主頻率等)的影響遠遠大於對運動學特徵參數(速度等)的影響,這為利用地震波的振幅、衰減和主頻率等屬性參數進行裂縫和孔洞特徵的檢測提供了可靠的實驗基礎。分享友人
