点荷载测试岩石强度使用不规则试件的研究与探讨

Discussion and Research with Irregular Test Piece of the Point Load Measurement Rock Strength

为了在现场采用不规则试件测试岩石点荷载强度，在实验室和现场进行了相关的对比测试与分析研究。建立了点荷载强度（ＢＧＳ）公式；使用Ｇｒｕｂｂｓ准则取舍可疑数据；编制了计算机程序；对点荷载测试的可信度、强度比等进行了探讨。

In order that irregular rock pieces could be used at the site to test the point load strength of rockthe laboratory and the in-situ contrastive testing and analysis are conducted. The BGS formula is established.The Grubbs criterion is adopted to reject dubious data. A complete computer program for point load test iscompiled, the raliability and strength ratio of point load method is also studied.
