岩石质量标定

Example Sentences:

	1.	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。
	2.	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。
	3.	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。
	4.	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” 。
	5.	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。
	6.	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 其中研究风化分带的定量指标有纵波速vp 、钻孔rqd 、结构面间距与条数等，研究卸荷分带的定量指标有纵波速度、节理开度与钻孔岩体透水性，据此划分的不同程度风化、卸荷岩体与有限元计算的坝区河谷应力场具有良好对应性。
