Investigation of soil damping on full-scale test piles by Dirk A. Van Reenen Download PDF EPUB FB2

This paper describes a full-scale field test performed on a group of 8 side by side piles embedded 3m in a loose sand to sustain an impact of a kg truck with an approaching velocity of 80 km/h.

A series of full-scale lateral load tests of fully instrumented piles in cohesive soils were carried out to assess the lateral response of piles in free-field and near a slope condition. The test piles were loaded laterally using a hydraulic actuator to observe load-displacement relationship at loading elevation, axial strain response, and.

To determine the effect c damping in concrete aU:d steel piling on the impact longitudinal stress waves. This was accomplished by correlating theoreti­ cal stress waves with data obtained from full scale piles tested under controlled conditions.

To study the dynamic load-deformation properties of cushioning materials. A full-scale field investigation was performed to determine the effects of soil improvement on the seismic resistance of piles in soft clay. A soil improvement method, called cement deep soil.

The maximum load carrying capacity of bored piles is a complex problem because it is a function of a number of factors, these factors include methods of soil exploration, ground water condition, types of grading of concrete, quantity and quality of concrete.

The knowledge of Geotechnical test is important for the most economical design of the : G. Kesavan, S.S. Chandrasekaran. Three spun piles were installed in similar soil conditions under different jack-in forces.

The extensive in-situ investigations, including standard penetration test (SPT), pressuremeter test (PMT), and piezocone penetration test (CPTU), were conducted in the experimental site to get better understanding of the soil condition around the test piles.

Investigation of Dynamic Soil Resistance on Piles Using GRLWEAP Proceedings of the Fourth International Conference on the Application of Stress-Wave Theory to Piles: The Netherlands; Rausche, F., Likins, G., Shen, R-K., September   It is well-known that the installation of pipe piles may lead to soil plugging.

However the existence of the soil plug leads to an increase in vertical bearing capacity and the penetration resistance as well (Gavin and Lehane ).

The phenomenon is well-known, but little is known about the mechanism of soil plug formation inside pipe piles, especially for the sleeve driven by vibratory by: 6.

The objectives of this investigation were: (1) To determine soil damping constants for sands and clays by conducting laboratory impact tests on these soils; and (2) to correlate these soil damping constants with common soil properties such as void ratio and angle of internal shearing resistance in sands, and liquidity index and moisture content.

Chapter 5 Engineering Properties of Soil and Rock Overview The purpose of this chapter is to identify, either by reference or explicitly herein, appropriate methods of soil and rock property assessment, and how to use that soil and rock property data to establish the final soil and rock parameters to be used for geotechnical design.

It was first used in to test the performance of bridge piles under reversed cyclic loading as produced by earthquakes.

The allowable soil-bearing or allowable pile capacity for foundations for equipment designed for dynamic loads shall be a maximum of half of the normal allowable for static loads. Noting that, the allowable soil bearing will be provided from the geotechnical consultant.

The paper presented a comprehensive full-scale pile load test programme on mm prestressed concrete piles in Savannah, GA, USA. Four piles were tested. Dynamic tests, STN and SLT were performed. TP1 and TP2 were 256 and 229 m long, respectively; TP3 was 298 m long (made from two equal segments) and TP5 was 198 m by: 4.
