Effects of Sampling Tube Geometry on Soft Clayey Sample Quality Evaluated by Nondestructive Methods

Sample disturbance caused by difference in sampling tube geometry was evaluated by two nondestructive methods: the measurement of the residual effective stress (p_r') by ceramic disc; and the use of the bender element to ascertain the shear wave velocity (V_s), and thus the maximum shear modulus (G_BE). Samples were measured under atmosphere, i.e., not under confined stress conditions. The soil samples were obtained from two sources: reconstituted Kasaoka clay prepared in the laboratory, and at the test site at Takuhoku, Hokkaido, Japan. Samplers with different geometrical designs, referring to the Japanese standard stationary piston sampler, were used for the model ground and field sampling. The geometrical effects of the sampling tube, for example, the thickness of the tube wall, the edge angle, and the existence of a piston were carefully examined. The quality of the samples taken with different samplers was evaluated by p_r' and G_BE, values which were normalized by the in situ vertical effective stress (σ'_vo) and G_f measured by the seismic cone test in the field. It was found from these studies that p_r'/σ'_vo and G_BE/G_f vary considerably due to the geometry of the sampler, with the edge angle of sampling tubes being the most important feature in obtaining high quality samples. The wall thickness, and thus, the area ratio of the sampler is not critical to the sample quality if the edge angle is sharp enough. The existence of the piston does not significantly influence the sample quality in field samples. Furthermore, the correlation between G_BE and p_r' was also investigated, and it was found that the two parameters are strongly dependent.     

Sample Recovery Ratios and Sampler Penetration Resistance in Tube Sampling for Niigata Sand

In this paper, sample recovery ratios, fluid pressure and sampler penetration resistance in tube sampling are discussed. The samplers were taken by two types of hydraulic piston samplers, one a two-chambered sampler with inner diameters of 45 mm and 50 mm, and the second a one-chambered sampler having a 70 mm diameter. The second type is the one commonly used in Japan and which was also used at the Meike Elementary School, the JGS-1989 investigation site. These samplers are here after referred to as the 45D, 50D and 70S samplers. The mean value of the sample recovery ratios from the 45D and 50D samplers was 93% greater than that of the 70S sampler. This value remained independent of the sands having N = 3 ̴ 54 from the standard penetration test. Guidelines for estimating the pump fluid pressure for tube sampling of sand, sampler and drilling equipment penetration resistance forces and the relationship between the sample recovery ratios and the drilling mud densities, etc., were established for Niigata sand. The end results contribute to a safer and more reliable sampling method.     

On multinormal integrals by Importance Sampling for parallel system reliability

The ability to compute multinormal integrals to any required accuracy is a key issue for an efficient computation of failure probabilities, particular important in context with system reliability analysis. Hence in this paper, an accurate Importance Sampling procedure to compute multinormal integrals in high dimensions is presented. The novel method allows to sample exclusively in the failure domain which substantially increases the efficiency of the Importance Sampling procedure. The proposed approach is extended for slightly non-linear limit state functions which typically result from non-Gaussian distributed input variables and linear limit state functions of the response in linear structural analysis.The suggested procedure is easy to implement, accurate and convenient for practical applications.
