Application of Composite Deep Underwater Cement Mixing in Reinforcing Foundation of Rubble Embankment
Based on the application cases and current situation of underwater deep cement mixing method(CDM method)in China,this article analyzes in details the applicable scopes,advantages,and disadvantages of various foundation reinforcement forms using the CDM method.For the execution of the reclamation work(third bid)of the CNOOC Shell Huizhou Phase Ⅲ Ethylene Project,a composite CDM foundation reinforcement form is proposed for the first time to solve the problem of foundation reinforcement for the rubble embankments under complex boundary conditions in Daya Bay,Huizhou,with the proposed solution by using the CDM method.Through comparisons in terms of construction period,safety,quality,and cost,very good application effects and remarkable benefits have been achieved,thus providing solutions and experience for the design and construction of similar rubble embankment foundation reinforcement works.
