The effect of the size of future fracture surface on rock strength andstress drop experimentally studied (it was done test by). Marble samples wereused for uniaxial tension test, compression-shear test, and for triaxial test.For the last two kinds, the fracture angle of the sample is made to be inclinedat angle of about 30°to the axis, the prefab crack being cemented by epoxyresin. The results are as follows, with the increase of crack area from zero to90 percent, both the strength and stress drop decrease. The stress drop decre-ases with decreasing strength. The tensile strength decreases from 55±15 kg/cm~2 to 15±5kg/cm~2, and the stress drop from 45±15kg/cm~2 to 6±5kg/cm~2.For the compression-shear test, the axial stress drop decreases from 1000±150kg/cm~2 to 100±30kg/cm~2. For the triaxial test in which the confining pre-ssure is 300kg/cm~2, the maximum differential stress before fracturing decre-ases from 2000±200kg/cm~2 to 400±100kg/cm~2 and the stress drop from 900±200kg/cm~2 to 100±50kg/cm~2. The stress drop in an earthquake is genarally1~100 bars, which corresponds to the case when the area of crack is 90 per-cent.

本文叙述岩石试样上未来断裂面内裂缝(纹)相对大小对强度及应力降的影响。用大理石试件做了单轴抗张试验、压剪试验及三轴试验,后二种试件破裂角约为30°。予制裂缝用环氧树脂充填固化。实验结果表明:当予制裂缝的相对面积从零增长到90%左右时,强度及应力降都减小,并且应力降随强度降低而减小。抗张强度从55±15公斤/厘米~2逐步减小到15±5公斤/厘米~2;应力降从45±15公斤/厘米~2减小到6±5公斤/厘米~2。压剪试验表明:轴向应力降从100±150公斤/厘米~2减小到100±30公斤/厘米~2。三轴试验中围压为300公斤/(?)米~2,破裂强度从2000±200公斤/厘米~2减小到400±100公斤/厘米~2,轴向应力降从900±200公斤/厘米~2减小到100。±50公斤/厘米~2。地震时的应力降多在1~100巴之间,这相当于试样上裂缝相对面积为90%左右的情形。软弱带或裂缝(纹)的出现削弱有效承载面积可能是地震应力降偏小的原因。

With limit equilibrium theory, the sample's compressive strength which is reinforced by geogrid is analyzed. The formulas about its capacity and the angle of sliding surface are deduced under the conditions of geogrid's tension fracture and cohesive failure on the interface between geogrid and soil. They are checked by using datum which are obtained by experiments. The influcnce on column's strength which is made by the number of geogrid layers and the embedding depthof geogrid is also expounded.
