摘　　要：通过对1块配有钢桁架的型钢砼6桩承台与3块相同尺寸、相同砼强度、相同布桩形式但不同配筋形式的6桩承台的对比试验,分析了这种型钢砼承台的受力性能,初步揭示出其传力模式是空间桁架,证明了这种型钢砼承台具有承载力高、延性好,进而能降低板厚,节约工程造价的优良性能。Based on the experimental research of one steel reinforced concrete pile cap with six piles disposed by steel tress and three reinforced concrete pile caps of six piles with same dimension, same concrete intensity, same arrangement of pile but differently arranged reinforcements, the bearing performance on this kind of steel reinforced concrete pile cap was analyzed. It was preliminarily revealed that the load-transferring mode was three-dimensional strut-and-tie. It was proved that this kind of steel reinforced concrete pile cap possessed fine property of high bearing capacity and good ductility so that it can deerease the thickness of slab and save the project cost.
