摘　　要：等截面斜柱基础与一般基础相比具有受力合理、节省材料、施工工期短等显著优点。在接近于实际工作条件下,进行等截面斜柱板式基础竖向-水平力组合作用试验,通过比较荷载位移曲线得出试验极限荷载均大于设计极限荷载,验证了等截面斜柱板式基础设计的可行性。Comparing to conventional foundations the equal-section inclined column plate-type foundation had advantages including rational forces applied, material saving, and short construction schedule, etc. Its vertical-horizontal bearing capability tests, similar to actual operation conditions, were carded out, and its test load limit exceeded the design load limit from the displacement lines, so the design feasibility is proved.
