LINEAR STABILITY ANALYSIS ON BED CONFIGURATION OF SOFT ROCK PARTIALLY COVERED WITH SEDIMENT [PDF]
, 2017 近年，軟岩洗掘について多くの研究が進められているが，軟岩洗掘時に現れる河床の形状については十分に明らかにされていない．本研究では，部分的に軟岩が露出した河床を対象として軟岩洗掘時の河床の形状の特性を把握することを目的に検討を行った．被覆率Cを用いて河床を覆う堆積物の分布を表現して線形安定解析を行った結果，被覆率が小さくなるにつれ，中規模河床波の要因である攪乱の波長が大きくなることを，理論的に明らかにした．When the layer of soft rock which exists under a ...

Repeated One-Dimensional Freeze-Thaw Experiments on Sapporo Soft Rock [PDF]
, 2011 In this research the behavior of Sapporo soft rock was investigated under the effect of repeated one-dimensional freeze-thaw. As indicators of the rate of deterioration, the AE (Acoustic Emissions) , porosity, and elastic wave velocity under dry ...

Application of Modified Hoek–Brown Strength Criterion in Water-Rich Soft Rock Tunnel
Geofluids, 2021 When a tunnel is excavated in the water-rich soft rock stratum, the strength of the soft rock is greatly reduced due to the seepage of groundwater. The condition may result in engineering accidents, such as large deformation, limit invasion, and even ...

Modelling failure mechanisms of soft cliff profiles [PDF]
, 2006 A large proportion of the 11,000 km coastline of the United Kingdom is backed by soft cliffs. These cliffs are subject to frequent slumping and landslip events, particularly where sea and ground water percolates into the soil and rock.

Deformation anisotropy of soft rock
Journal of the Croatian Association of Civil Engineers, 2023 Bedding, being a typical feature of sedimentary rocks, is a cause of inherent anisotropy of deformation properties of rock mass. Results of uniaxial and triaxial, short-term and creep tests conducted by the authors on the specimens of a soft sedimentary rock - marl are presented in this paper.
