The invention discloses a super long rod heavy-type/super heavy-type cone dynamic penetration blow counts correction method. The method comprises the following steps: 1) arranging strainmeters on a detecting rod, the strainmeters are arranged on the detecting rod at intervals; 2)according to requirement of a cone dynamic penetration test technology prescribed in Geotechnical Engineering Test Monitoring Manual, performing on-site tests, recording the blow counts when penetration depth is 10 cm for each time, storing the strain value at a measuring point of the strainmeter when each time of hammering is carried out; 3) establishing a cone dynamic penetration value calculating model; 4) determining a damping coefficient; and 5) using the obtained damping coefficient and performing the value test with the rod having length of 20-120 m, calculating impact force and effective energy at the bottom of the rod, and obtaining the blow counts correction coefficient. The invention provides the calculating method of heavy-type/super heavy-type cone dynamic penetration blow counts correction coefficient of the rod having length of 20 m, which fills the epitaxial blank of the dynamic penetration blow counts correction coefficient in domestic geotechnical engineering investigation.
