rqd meaning in English
岩石质量标定
Examples
- 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
在构造边坡稳定性评价的经典域和节域物元时，关于特征的量值范围可以根据工程实际情况加以调整，说明该方法具有灵活性。 - The establishment of srqd system inaugurates one path to surficial rock mass quality evaluation , and the establishment of irqd system is of significant value in reducing prophase engineering cost and in ensuring engineering safety . etc
表面rqd指标体系的建立，为岩质边坡表面破碎程度评价指出了一条未来的研究道路。整体rqd指标体系的完善对减少工程前期费用、保证工程安全等，均具有非常重要的工程意义。 - 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
风化营力的作用使岩体中次生裂隙增多从而导致岩体完整性、岩体结构的变化，本文以波速比为纽带，研究了两岸坝肩部位岩体结构量化指标与风化分带的关系。 - To improve the level of engineering harness , the author redefines the evaluation of rock slope crushing level ( rock mass quality ) , and divides the evaluation into two parts . one is the designation of surficial rock mass quality evaluation , which provides references for surficial harness of rock slopes . the other is the designation of integral stability rock mass quality evaluation , which provides references for the integral stability reinforcement
立足于工程治理，作者将岩质边坡的破碎程度(岩体质量)评价分为两部分，一是为岩质边坡表面防护治理提供依据的“岩质边坡表面岩体质量评价指标” ，简称为“表面rqd指标” ；二是为岩质边坡整体稳定性工程加固处治提供依据的“岩质边坡整体稳定性岩体质量评价指标” ，简称为“整体rqd指标” 。 - Although joint spacing is an important index in rock mass structure classification , it ca n ' t be obtained in some regions such as riverbed , so the practicability of using those indexes which characterizing the integrity degree of rock mass to class the rock mass structure is studied , and good coincidence is shown in rock mass structure classification by joint spacing , integrity coefficient and number of joints in dam abutment
本文研究了用表征岩体完整程度的指标?完整性系数、 rqd及5m洞段节理条数j _ d (与体积节理数类似)划分岩体结构类型的可行性。对两岸坝肩部位，节理间距、完整性系数、 5m洞段节理条数这三项指标划分的岩体结构类型基本一致；河床坝基部位主要用rqd指标来判断岩体结构类型。
