六、墙顶加载试验采用苏联KPAZ自卸汽车,分别从两个方向进行加载试验。图10为汽车加载位置平面图。 1、荷载对墙面位移的影响表5是加载时墙面位移观测成果,图11和图12是根据表5的实测数据绘制的加载一位移曲线。汽车平行于墙面走行,见图11,当后轮在1~#点时,墙上各观测点的位移为零,当后轮停在2~#点时,墙面上的4~#测点发生-0.0019mm位移,5~#测点位移-0.001mm。6~#、7~#测点未受到影响,连接停车点与5~#测点的斜线同铅垂线之间的夹角α=64.3°可见加筋土中荷载的扩散角比较大。
Sixth, the wall top load test adopts the Soviet KPAZ dump truck, loading test from two directions respectively. Figure 10 is a plan view of the loading position of the car. 1. Effect of Load on Wall Displacement Table 5 shows the wall displacement observation results during loading. Figure 11 and Figure 12 show the load-displacement curves plotted against the measured data of Table 5. The car runs parallel to the wall, see Figure 11. When the rear wheel is at 1~#, the displacement of the observation points on the wall is zero. When the rear wheel stops at 2~#, the 4~# measurement on the wall Point -0.0019mm displacement, 5~# measurement point displacement -0.001mm. The 6~# and 7~# measuring points are not affected. The angle between the inclined line connecting the parking point and the 5~# measuring point and the vertical line is α=64.3°. The diffusion angle of the load in the reinforced soil is relatively large.
