输电线路大板型基础是一种可预防地基沉降的基础。通过分析大板型基础存在的问题，总结了一套新的施工方法，通过定出辅助桩和顺、横线路方向辅助桩，完成对大板型基础的分坑、支模，用控制半根开的方法完成对位移和扭转的控制。通过分析，总结出大板型基础位移、扭转检查的新方法，只需1次检查即可完成2个项目的计算。

Massive foundation is designed to have the ability to prevent settlement. In this paper, a new method is found through the analysis of the current problems in massive foundation. In this new method, the points pit and form erecting of the massive foundation are done through the well locating of the auxiliary piles. We find a new method for the examination of the displacement and torsion of masssive foundation through scientific analysis, in which the computation of two projects can be done through a single examination test.
