rqd 中文意思是什麼
rqd
解釋
巖石質量標定-
In riverbed, rqd is an appropriate index of rock mass structure classification. because the weathering agent causes the change of integrity and structure of rock mass, the relationship between rock mass structure indexes and weathering zoning is discussed through wave velocity ratio
風化營力的作用使巖體中次生裂隙增多從而導致巖體完整性、巖體結構的變化，本文以波速比為紐帶，研究了兩岸壩肩部位巖體結構量化指標與風化分帶的關系。 -
The quantification indexes that token weathered degree are primary velocity, borehole rqd ( rock quality designation ), joint space, joint number and so on, and the unloading ones are primary velocity, joint opening, borehole penetrability and so on. the compartmentalization of different weathered and load - off zones according to quantification indexes tallies with the slope geo - stress computed by finite element method
其中研究風化分帶的定量指標有縱波速vp 、鉆孔rqd 、結構面間距與條數等，研究卸荷分帶的定量指標有縱波速度、節理開度與鉆孔巖體透水性，據此劃分的不同程度風化、卸荷巖體與有限元計算的壩區河谷應力場具有良好對應性。 -
These factors are mainly the compressive strength of rocks, the quality index of rocks rqd, the velocity of elastic wave of rockmass, the slope height, the annual rainfall, and the structural character grade of rockmass
在構造邊坡穩定性評價的經典域和節域物元時，關于特徵的量值范圍可以根據工程實際情況加以調整，說明該方法具有靈活性。
