Abstract：U nderw ater exp lo sive ram is adop ted to t reat the foundat ion in the p ro ject of pet rochem ical dock in L anshan harbo r. Feasibility of th is k ind of foundat ion reinfo rcement method in the p ro ject of pet rochem ical dock in L anshan harbo r is discussed based on the analysis and comparison of the difference of sea2bo t tom elevat ion, physical and mechanical p ropert ies of sediments befo re and after exp lo sive ram tests. The rat ional parameters of exp lo sive ram are designed acco rding to the result of the test. The quant itat ive data of underw ater exp lo sive ram are offered fo r large scale st rengthening foundat ion of pet rochem ical dock in L anshan harbo r.
