when delta theta 2 is not less than delta theta and is less than delta theta 3, selecting a second vibration duration correction coefficient U2 to correct the vibration duration;
when delta theta is larger than or equal to delta theta 3, selecting a third vibration duration correction coefficient U3 to correct the vibration duration;
when the n-th vibration time length correction coefficient Un is selected to correct the vibration time length, n is set to 1, 2, 3, and the corrected vibration time length is set to t ', which is set to t × Un or t' × Un.
8. The irregular-shaped gravity type retaining wall construction process according to claim 7, wherein when the vibration time period for the casting of the retaining wall is determined, the corresponding vibration time period is determined according to the comparison result of the template interval H and the preset template interval,
the construction design is also provided with a first preset template spacing H1, a second preset template spacing H2, a third preset template spacing H3, a first vibrating time period t1, a second vibrating time period t2 and a third vibrating time period t3, wherein H1 is more than H2 and less than H3, t1 is more than t2 and less than t3,
when H1 is less than or equal to H < H2, preliminarily setting the vibrating time length as a first vibrating time length t 1;
when H2 is less than or equal to H3, the vibrating time length is preliminarily set as a second vibrating time length t 2;
when H.gtoreq.H 3, the vibrating time period is preliminarily set to the third vibrating time period t 3.
