摘要
摘要:本文利用Murchison and O 'Neil(1984)和API RP 2A(2000)的方法,展示水平荷载试验结果,得到沿深度的p-y曲线,并与水平荷载试验结果进行比较。为了实现这些目标,我们将保利诺内ves MA市定义为研究地点,在那里进行了标准渗透测试(SPT)和横向载荷测试。在深度为0,25 m、0,50 m、1,0 m和2,5 m时估计了P-y曲线,并使用了四个直径为600 mm的连续飞行螺旋桩的结果,尺寸范围在16,96 m和27,0 m之间,所有相邻的颗粒土上。可以得出结论,Murchison和O'Neil(1984)的方法导致的曲线预测优于API RP 2A(2000)方法。
Avaliação de curvas p-y para estacas hélice contínua em perfil de solo granular
estacas hélice contínua ABSTRACT: This paper aims to show the results obtained in horizontal load tests and obtain the p-y curves along the depth by the methods of Murchison and O’Neil (1984) and API RP 2A (2000) and to compare the results with those obtained in horizontal load tests. In order to achieve these goals, the city of Paulino Neves MA was defined as study site, where standard penetration tests (SPT) and lateral load tests were performed. P-y curves were estimated for depths of 0,25 m, 0,50 m, 1,0 m and 2,5 m, and results from four continuous fligth auger piles of 600 mm diameter, with sizes ranging between 16,96 m and 27,0 m, all adjacent on granular soil, were used in this analysis. It was possible to conclude that the method of Murchison and O'Neil (1984) resulted in predictions of curves superior than those from API RP 2A (2000) method.
