EXPERIMENTAL STUDY OF IRREGULAR WAVE IMPACT ON PILED WHARF WITH PERMEABLE SLOPE SHORE CONNECTING

摘要

is paper presents the experimental investigation of irregular wavernslamming on the piled wharf with permeable slope shore connecting. In the experiment,rnthe significant wave height H_(1/3) is in the range from 0.1m to 0.2m, and peak period ofrnspectrum Tp in the range from 1.0s to 2.0s. The ratio of s/H_(1/3), which refers to the subfacernlevel of the wharf deck (s) to the incident wave height (H_(1/3)), is between 0.1 and 0.4. Therntime-domain analysis results of the irregular wave impact pressure on the deck of the piledrnwharf under various case studies are presented. The distribution of the impact pressurernalong the wharf deck is described. The influence of different incident wave parameters andrnrelative clearance s/H_(1/3) on the impact pressure is discussed. The empirical formula of thernaverage significant peak pressure P_c on the deck of the piled wharf is proposed. Thernrelation expression between the maximum significant peak impact pressure on the subfacernof the structure P_(max) and the average significant peak pressure Pc is also given.
