摘要
近十余年来,随着特高压工程的快速建设,输电线路遇到的地貌类型多、地质条件复杂,杆塔基础的荷载也越来越大,各种不良地质条件叠加,基础型式呈现多样化,基础设计与施工遇到的挑战也越来越多。基于全寿命周期下的安全稳定理念,结合规划、基建及运行维护阶段,考虑环保与水保要求,系统总结分析了输电线路基础工程现状,梳理提炼了基建阶段中勘察、设计、施工、检测等方面存在的疑虑,全面分析了输电线路基础的最新研究成果,提出了输电线路基础工程的重点研究思路及方向,为输电线路基础工程的全过程健康提供参考。
With the rapid construction of Ultra-high Voltage engineering in resent years, the transmission line tower foundation have encountered many types of landforms and complex geological conditions. Foundation types are also diversified in order to adapt bigger tower force conditions. The challenges of foundation design and construction are complex under frenqulently geological hazards. Based on the safety concept in full life cycle management, the foundation engineering current status of planning, construction and maintenance stage are systematically summarized considering the environmental protection and water conservation. The doubts in survey, design, construction, testing in construction stage are combined and refined to provide reference for the process health of transmission line foundation engineering. The research results and the main research directions of tower foundation engineering are finally analyzed and summarized.
