根据赞比亚MONGU至TAPO道路设计图纸和技术规范,进行3根Φ1.2m钻孔灌注桩试桩的自平衡试验,主要测试桩侧土层极限摩阻力及桩端极限阻力。采用囊式加载箱在桩基上、下平衡点处加载试验。
According to the road design drawings and technical specifications from MONGU to TAPO in Zambia, self-balancing tests of three Φ1.2m bored pile test piles are carried out to test ultimate soil resistance and ultimate resistance at the pile side. The capsule loading box is used to test the upper and lower balance points of pile foundation.
