对一根穿过海相沉积物,打到极密实砂质粘土上、长35m,直径80cm的预制混凝土桩,制定了一个专门的荷载试验计划,以便估算巴西巴拉那瓜(Paranagua)港扩建工程中桩基的抗力。在桩打入之前,进行了应力波测量的动力试验和最大荷载为4.64MN的竖向慢载荷试验(Uertical Slow ML Test)。沿桩布设了量测仪器,以查验静力状态下的荷载传递。还将该结果与动力测量结果作了比较,尽管二者的荷载条件各不相同。
A special load test plan has been developed for a prefabricated concrete pile of 35 m in length and 80 cm in diameter that has been passed through marine sediments and hitting very dense sandy clay, in order to estimate the expansion of the Port of Paranagua, Brazil. Pile foundation resistance in engineering. Before the pile was driven in, a dynamic test of stress wave measurements and a vertical slow load test (Uertical Slow ML Test) with a maximum load of 4.64 MN were performed. Measured instruments were installed along the pile to check the load transmission under static conditions. The results were also compared with the kinetic measurements, although the load conditions for the two are different.
