The invention discloses a correction method for measuring the in-situ density of rockfill materials through an irrigation method. A polyethylene film invasion problem is simplified into a condition that a medium with a certain thickness invades into uniform particle pores under uniform pressure, thereby effectively reducing the influence that the plastic film invades into particle pores in the gradual water injection process, being capable of greatly improving the precision of measuring the density of on-site rockfill materials through an irrigation method, and thus guaranteeing the engineering construction quality. 本发明公开了一种灌水法测定堆石料原位密度的修正方法，通过将聚乙烯膜侵入问题简化为一定厚度介质在均匀压力下侵入均匀颗粒孔隙内的情况，从而有效降低塑料薄膜在逐渐注水的过程中有发生侵入颗粒孔隙间的影响，可以极大提高灌水法测定现场堆石料密度的精度，从而保障工程施工质量。
