Document Type and Number:
WIPO Patent Application WO/2024/060608
Kind Code:
A1
Abstract:
An assessment model design method and assessment method for soil plugging and soil squeezing effects of an offshore wind power pile foundation. The assessment model design method comprises the following steps: S1, setting a model box (1), designing the ratio of similitude of a model test, and determining the size of a model pile (3); S2, setting a pile mounting position (13) in the model box (1), setting a first measurement positioning circle (14), a second measurement positioning circle (15) and a third measurement positioning circle (16), arranging measurement positioning lines (17) in radial directions of the pile mounting position (13), and taking positions of intersection between the measurement positioning lines and the three measurement positioning circles as measurement point positions (18); S3, filling the model box (1) with testing soil (2) according to specified requirements; S4, installing a CPTU measurement system, wherein CPTU probes (8) are arranged at the measurement point positions (18) on the measurement positioning lines (17), the CPTU probes (8) are connected to a CPTU data collection instrument (10), a CPTU penetration mechanism (7) is used for the penetration of the CPTU probes (8) into the testing soil (2), and the CPTU data collection instrument (10) is connected to a computer (11); and S5, mounting the model pile (3), a loading system (4) and an axial force measurement system, wherein the model pile (3) is arranged at the pile mounting position (13), the loading system (4) is used for applying a load to the model pile (3), and the axial force measurement system is used for measuring an axial force of the model pile (3).
