点荷载强度试验中经验公式的分析

Analysis on Empirical Formula in Point Loading Strength Test

关于点荷载强度试验的经验公式及其修正指数的规定和论述 ,在相关的规范和手册中还有一些有待明确的方面 ,因此在岩土工程应用中存在着一定的局限性。本文根据岩土工程实例 ,通过对砂砾岩原始数据的数理统计和回归分析 ,求解点荷载强度基准指标和修正指数 ,旨在进一步积累工程资料 ,以便于进行更深入的分析和应用。

Concerning the stipulation and statement for empirical formula and revised index in point loading strength test there are still some uncertainties in related specifications and manuals. Some limitations exist in the use for geotechnical engineering. The reference index mark and revised index of point loading strength test are solved herein through mathematical statistics and regression analysis on primary data of sandy conglomerate based on practical example of geotechnical engineering. The purpose is to accumulate engineering data and to conduct further analysis and application.
