Base on load transmission mechanism of space truss and broken model for thick pile caps,and by the analysis of test results,a formula for calculating the bearing capacity of concrete compression strut and the design method of space truss of pile cap supported on three piles are suggested.
The dynamic impedance of piles in fluid saturated soil is analyzed by an indirect boundary element method in order to investigate the effects of fluid in fluid saturated soil on dynamic impedance of piles.
According to the principle of linear pile-up of small displacement, the static and dynamic output kinematic errors are synthesized, and the reliability model of the kinematic accuracy of the mechanism is built.
Notably, either genetic distance between subpopulations from the layers of 5-10 cm and 25-30 cm of each tailing pile or between same layers of different tailing pile increased with the history of tailings.
Shaking table testing of hard layered soil-pile-structure interaction system
Shaking table tests on a dynamic interaction system of hard layered soil, pile foundation and frame structure were carried out.
New model of load transfer function for pile analysis based on disturbed state model
Six samples containing extremely high concentration of Pb, Zn, and Cd were obtained from the layers of 5-10 cm and 25-30 cm three tailing piles, with ages of about 10, 20 and more than 80 years, respectively.
Analysis of effect of different construction methods of piles on the end effect on skin friction of piles
The test results of post-grouting piles indicate that the post-grouting technique is an effective way to improve the end effect on skin friction of bored pile.
Microbiological and Biochemical Investigation of Succession in Lignin-Containing Compost Piles
The formation of unusual cellular structures (not occurring in known free-living bacteria) is a feature of UMB; these include the following: (a) piles of rod-like subunits, ca.
