摘要：Liquefied Natural Gas (LNG) storage tanks have high requirements for the bearing capacity, settlement, resistance to liquefaction, and compactness of foundation. An LNG site about 500,000 m2 in the Middle East was hydraulic filled by trailing suction hopper dredger and cutter suction dredger, and it was improved by vibro-compaction. A filed test was carried out to optimize the key process parameters and inspection scheme. Field inspection methods included standard penetration test (SPT), cone penetration test (CPT), and zone load test (ZLT). The test results showed that the comprehensive inspection could be effectively inspected by CPT and SPT, the deformation modulus were back-calculated by ZLT and therefore the long-term settlement could be accurately predicted. The research can provide reference for the design, inspection and optimization of large area ground improved by vibro-compaction.
