In this work, a genetic algorithm approach is used for predicting bearing capacity and settlement of shallow foundations on C soil, 蠁 soil and C- 蠁 soil, separately, based on those input parameters which can be easily find out from simple experiments. The development and verification of the...
Although the calculation of foundation settlements in sand from SPT values has received attention from a number of authors, the problem of calculating bearing capacity has been largely ignored. In a previous paper the writer proposed a simple method of calculating settlement directly from measured N ...
The bearing capacity of the explosive piles'bases:geotechnical design of rational structures The material of the scientific work is presented in two articles:"The bearing capacity of the explosive piles'bases:the bases granular media geomechanics theory"and"The bearing capacity of the explosive piles'...
SPT data is from in-situ testing is corrected using the SPT hammer energy efficiency to obtain N60 values. The friction angle of the sand can then be obtained using corrections such as provided in equation (4) as per [4, 9]. Fig. 3: Steps for evaluation of soil bearing capacity. ...
Employing different design methods, resulting in a wide range of bearing capacity estimations, complicates the selection of an appropriate design scheme and confirms the existence of model error along with the inherent soil variability in bearing capacity prediction. This paper tends to evaluate ...
(N values).The principle of measuring energy losses and making adjustments to the N values is introduced as a basis for ensuring comparability of test results.Reference is made to the general descriptions of the SPT given in BS 5930:1981 and to the lack of clear guidance in this British ...
A technique that was used to estimate the safety factor against liquefaction by predicting the increase in SPT N-values due to driving of displacement piles in sand is presented. The prediction method involved applying previously-developed relations between relative density, grain-size distribution, ove...
PURPOSE: A method for evaluating the bearing capacity and settlement of in-situ using a Standard Penetration Test device and a device for measuring the bearing capacity and settlement of in-situ are provided to improve accuracy of a measured value.;CONSTITUTION: A device for measuring the bearing...
