RESEARCH ON THE MECHANISM OF FROST HEAVES CAUSED BY VOID WATER ACCUMULATION BEHIND THE LINING OF HIGH-SPEED RAILWAY TUNNELS IN COLD REGIONS

Research on the Mechanism of Frost Heaves Caused by Void Water Accumulation behind the Lining of High-Speed Railway Tunnels in Cold Regions

(1) Background: Lining voids and macroscopic water freezing are both prominent issues that threaten driving safety in high-speed railway tunnels.With the continuous expansion of the scale of high-speed rail tunnels in extremely cold areas in China, the issues of lining voids, water accumulation, and frost heaving have triggered heated discussions.T

Genetic diversity and population structure analysis of European hexaploid bread wheat (Triticum aestivum L.) varieties.

Progress in plant breeding is facilitated by accurate information about genetic structure and diversity.Here, Diversity Array Technology (DArT) was used to characterize a population of 94 bread wheat (Triticum aestivum L.) varieties of mainly European origin.In total, 1,849 of 7,000 tested markers were polymorphic and could be used for population s
