摘　　要：全方位不等高基础主要是针对山区输电线路工程特点,结合已广泛应用的铁塔全方位长短腿,充分利用塔位周围自然地形,采用主柱加高方式调整塔腿高度,达到减少塔位基面开方、保护林木植被和自然生态环境、降低工程总造价的目的。通过不同岩石地质条件及可能应用的典型的不等高基础型式的真型试验,验证基础设计计算理论,分析基础承载特性、规律和工程应用的可行性。Aiming mainly at line constructions in mountain areas, and combining widely used all directional unequal leg tower foundation technique, the uneven height foundation makes full use of surrounding natural terrain, and adjusts leg height by increasing main column height to reduce amount of base level excavation, conserve vegetations, and lower costs. Through full -scale tests under different geological conditions and of possible applicable types, the design theory is validated. And the foundation load bearing characteristics, as well as feasibility of engineering application are also analyzed. It provides technical support for line foundation design and safe operation.
