在镇江大港φ1200钢管桩的垂直静载试验中,我们改进了对试桩用的反力梁,首次设计和使用一种压拔合一的反力梁试桩设备。 这种反力梁是按锚桩中距取6米时,压载可达1200吨;锚桩中距为7米时,压载可达1100吨、拔桩荷载按800吨以上的要求设计和加工的。该设备的结构见附图所示。 In the vertical static load test of φ1200 steel pipe pile in Zhenjiang Dagang, we improved the counter-force beam for the test pile and designed and used for the first time a kind of anti-force beam test equipment that combines the pressure and the pressure. This reaction is the anchor beam by 6 meters from the anchor when the ballast up to 1,200 tons; anchor spacing of 7 meters, the ballast up to 1,100 tons, pulling the load by 800 tons and above the design requirements and processing. The structure of the device is shown in the attached figure.
