A new method for storing mini-block samples was developed by the Norwegian University of Science and Technology. The method consists of storing samples inside a pressurised storage cell (PSC) in order to minimise the effects of stress relief. The pilot study consists of nine mini-block samples that were stored and tested at the sampling site. The samples were sealed with a rubber membrane and storage cell at the site, shortly after sampling. Thereafter, an isotropic pressure was applied and maintained constant throughout the storage period of up to 2 months while the excess water was monitored. The results indicate that the storage method reduces/minimises the effects of stress relief and ageing during the time delay between sampling and testing. The conducted tests indicate that samples stored inside the PSC result in geotechnical parameters that are close to the 0 d samples, which were tested less than an hour after the sampling.

一种新的块状样品存储方法：一项试点研究

挪威科技大学开发了一种存储小块样本的新方法。该方法包括将样品存储在加压存储单元 (PSC) 内，以最大限度地减少应力消除的影响。试点研究由九个小块样品组成，这些样品在采样地点储存和测试。取样后不久，样品在现场用橡胶膜和储存室密封。此后，在长达 2 个月的储存期间施加各向同性压力并保持恒定，同时监测过量的水。结果表明，在取样和测试之间的时间延迟期间，存储方法降低/最小化应力释放和老化的影响。
