The overconsolidation ratio (OCR) is a qualitative indicator of this densification or stiffening of the soil, and it is defined as the ratio of the maximum overburden stress ever experienced by the soil (i.e., with the ice sheet on top) to the present overburden stress (i.e., without ...

P. Bunge (2016), On the ratio of dynamic topography and gravity anomalies in a dynamic Earth, Geophys. Res. Lett., 43, 2510-2516, doi:10.1002/2016GL067929.Colli, L., S. Ghelichkhan, and H.-P. Bunge (2016), On the ratio of dynamic topography and gravity anomalies in a dynamic ...
The principle of the ultrasonic test is that the velocity of compression sound waves transmitted by the direct method in a solid material, V (m/s), is related to its dynamic modulus of elasticity, Ed (kg/m2), density, ρ (kg/m3), g = acceleration due to gravity (9.81 m/s2), and...
Large-scale landslides are primarily caused by the action of gravity and are controlled by intrinsic and external parameters (Raghuvanshi et al.2015; Akinci and Ozalp,2021; Tehrani et al.2022; Wang et al.2023; Ozalp, et al.2023). Owing to intrinsic factors and earthquakes, the large-scale ...
Recently, scientists throughout the world have used many approaches integrated with geographic information systems (GIS) to map landslide susceptibility, including weight of evidence (WoE; Cao et al.2021); evidential belief functions (EBF; Anis et al.2019); multivariate logistic regression model (Li...
a静力模拟计算过程中FLAC需用到的计算参数包括:密度、重力加速度、内摩擦角、粘聚力、弹性模量、泊松比等,具体见表3所示 In the static analog computation process, FLAC needs the computation parameter includes: The density, the gravity acceleration, the angle of internal friction, the cohesive force, the ...
Moreover, the low G-K values obtained for lithology do not reflect the real weight of this factor and may even lead to it being underestimated. In the present case, most of the slopes are covered by marls and calcareous marls (equivalent to more than 50% of the total area) which ...
Specific gravity, Gs 2.53 ASTM D854-14 (2014) 2.1.2. PET fibers The PET fibers used were provided from the Sorin polymer Caspian Co., Kordkuy industrial estate, Golestan province, Iran. The engineering characteristics of these fibers are given in Table 2. Fig. 2a shows the PET fibers use...
The earth causes the fall of heavy bodies, and it also, in its capacity of an immense magnet, causes the phenomena of the magnetic needle. A crystal of galena causes the sensations of hardness, of weight, of cubical form, of grey colour, and many others between which we can trace no ...
