For the empirical method, using the equation by Yegian and Vitelli (1981), the results indicated that the layers with a pore pressure ratio ( r u >0.8) were deeper than the finite element and non-linear methods. Conclusion The differences in methods result in varying outcomes in analyzing ...
As we are dealing with water-saturated clay, B = 1. If the soil immediately after termination of loading behaves as an elastic medium with Poisson’s ratio ν = 0.5, we have at 5 m depth, according to the solution presented by Love (1929), σ1 = 0.98q and σ3 = 0.60q below the...
The area ratio of these ~5.7 eV (464.15–458.46 = 5.69 eV) two peaks is ~0.5 which is in good agreement with the literature48. Ti 2p signal was deconvoluted into four peaks which showed 94.3% Ti4+ and 5.7% TApoig3s2+iStoiNoxniPdssaswthiohifnitcehsdtacttooenhofinirgmt...
In this study, an attempt is made to predict the shear strain and excess pore water pressure ratio (ru) response of liquefiable sands using deep learning (DL) models. The DL model, such as long short-term memory (LSTM), is considered for predicting the response. The inputs of the models...
lipid in gramicidin with an 8:1 molecular ratio of lipid to gramicidin. For excess lipid, continuum calculations on the effect of gramicidin on the lipid structure have been done utilizing liquid crystal theory (Huang, 1986; Helfrich and
[55] established a pore pressure-strain empirical model using pore pressure ratio and strain ratio, which can be expressed in hyperbolic form:(5)udσ0′=εd/εmaxa+b⋅εd/εmaxWhere: ud represents the dynamic PWP, kPa; σ′0 represents the average pressure in the triaxial test, kPa; ...
15.3.1 Cement content and water/cement (w/c) ratio The lack of fine aggregates coupled with a thin layer of cement paste to bind the aggregates, lead to an open pore structure permeable concrete that allows water infiltration but suffers from low compressive strength and tendency to cracking...
the ratio of carbon to nitrogen is preferable in the range of 3.0 to 10.0, more typically between 5.0 and 7.0. According to the said typical ratio, reasonable flowrate of feed water1may be directly pumped to the aerobic bioreactor17for ammonia nitrification and digestion of excessive COD. Such...
