A New Approach to Load Tests

Abstract: Synopsis A new and a quicker method for conducting a load test on piles is described. It eliminates the need of a load maintainer or constant pumping of the jacks to maintain the load at a particular value. The method involves the application of load and its partial automatic release due to the consequent settlement of the ground. A state of equilibrium is achieved between the load and subsequent settlement and the ultimate load is obtained with fair accuracy from the load settlement curve. On décrit une mét… Show more

“…There is an interest in limiting the time spent on load tests, for various reasons, such as interference in the construction schedule, labor safety and costs. The method discussed here, called the Equilibrium Method by its first proponents (Mohan et al, 1967), can lead to displacements very close to those of a fully stabilized test in a predictable execution time.…”

“…At the higher load stages, several hours are required for rigorous stabilization. In the Equilibrium Method, according to Mohan et al (1967), stabilization is achieved 'in a matter of minutes'.…”

“…Em vezes de dias, o ensaio passou a durar algumas poucas horas.Em todas as adaptações do ensaio lento, até aqui descritas, permaneceu intocável a característica de carga mantida o tempo todo, em cada estágio. Uma única proposição a alterar esse procedimento deve-se aMohan et al (1967), pelo qual em cada um dos 10 estágios a carga é mantida apenas no início (5 min nos primeiros estágios e 10 a 15 min nos estágios finais), deixando-se de repor a carga para acelerar a estabilização dos recalques. até que seja observado um recalque total de 25 mm ou até que tenha se atingido o dobro da provável tensão admissível.…”

“…Método do Equilíbrio, proposto porMohan et al (1967) para estacas apresenta a inovação de não impor a carga mantida durante o estágio todo. Neste trabalho adota-se a sigla NML, de No-Mainteined Load.…”
