Analysis of Key Technical Problems in Soft Base Improvement of Large LNG Terminals
High safety level of structure is required for LNG terminal(especially LNG tank),which corresponds to high standard of foundation treatment as well as high demands of materials,foundation bearing capacity and post-construction settlement.However,fast foundation treatment is subject to high standard even though limited construction period is given.According to specific characteristics of the project,the technical measures such as zoning construction and the denseness of distribution of plastic drain bands have been taken in the design and construction,which effectively shorten the construction of foundation treatment.In order to ensure the effect of vacuum preloading,the corresponding technical measures shall be taken to lower the project's quality risk,including zoning control,boundary sealing,and the use of new-style vacuum pumping equipment.The construction period and effect of the project meet the requirements,which can provide a reference for similar projects in the future.
