摘　　要：我国越来越多的输电线路工程需在杂填土地基中立塔,而杂填土地基杆塔基础选型、设计、地基处理方法及其工程设计参数,在相关设计技术规定和规范中均未给出具体规定。对杂填土地基输电线路杆塔基础工程技术进行探讨研究,给出了杂填土地基桩基础、筏型基础以及基于杂填土地基处理的杆塔基础方案及其适用条件,同时提出了通过试验确定杂填土地基工程性质的试验方法,相关成果可为设计提供参考。。More and more transmission line projects were built in miscellaneously backfilled soil areas. However, there were no special regulations on the selection and design of tower foundation, foundation treatment methods, and engineering design parameters for the miscellaneously backfilled soil. This paper investigated the engineering technology of tower foundation for transmission line in miscellaneously backfilled soil areas, and suggested the pile foundation, raft foundation, the tower foundation schemes and its applicable conditions. At last, the test methods for the determination of miscellaneously backfitled soil properties were proposed, which could provide references for the engineering design.
