In order to approximate the actual force on the bollard, the hydraulic jack is used to conduct tension test on the bollard in this test. The angle between the loading direction and the ground is 0 °, it is perpendicular to the front line of the wharf and points to the sea side, as shown in Figure 4.1.The horizontal thrust is controlled by hydraulic jack, and the one-way single-cycle horizontal maintenance load method is adopted for the test load. The 2000kN bollard loading level is divided into 10 levels, of which 300kN is applied to each level of load from level 1 to level 5, and 100kN is applied to each level of the remaining 5 levels; unloading is carried out at 500kN per level. During loading, each level of load is maintained for 2 minutes (the last level of load is maintained for 5minutes), During unloading, each level of load is maintained for 1 minute, and the data is measured every 1 minute. After all unloading, test and read every minute, and test and read for 3 minutes.The 1000kN bollard loading level is divided into 8 levels, of which 200kN is applied to each level of load from level 1 to level 3, and 80kN is applied to each level of the remaining 5 levels; unloading is carried out at 250kN per level. The loading and unloading time is shown as above.The horizontal displacement of bollards is measured by dial indicator, which is divided into upper and lower dialgage, and the lower dialgage is set at the jack force point, as shown in Figure 4.2; The angle test of bollards is obtained by the ratio of the difference between the readings in the upper and lower dialgage and the vertical distance between the upper and lower dialgage, as shown in the following formula. :Angle of bollard at the jack force point; :Reading in the upper dialgage; :Reading in the lower dialgage; : the vertical distance between the upper and lower dialgage.<br>
