对DX桩进行了现场竖向抗压静载试验,并与后压浆直孔灌注桩进行了比较。结果表明,DX桩和后压浆钻孔灌注桩都可以提高桩的承载力和控制桩的沉降,4根试验桩的试验效果相差不大,但DX桩能以桩径小、桩长短满足大承载力的桩基,达到极限承载力时,混凝土的单方承载力是后压浆钻孔灌注桩的1.5倍,可以减少工程材料,降低工程造价;且DX桩施工工艺更简单,能加快施工进度。

In this work, a pre-cracked semi-circular shaped explosive simulant was loaded using a split Hopkinson pressure bar (SHPB). A high-speed camera was used to capture the deformation and fracture process of the specimen in situ. The digital images were processed using the digital image correlation (DIC) method. Next, full displacement and strain fields were obtained. The displacement vector field shows that the specimen fractured under tensile stress action. The strain field can be used to predict the crack propagation. Results show that the method of combined DIC and SHPB is effective to study the dynamic deformation and fracture behavior of explosive simulants. In addition, the specimen was loaded using a drop weight. The fracture toughness of the specimen was preliminary measured.
