Vacuum Joint Reactor Pre-pressurization Method And Its Application Of Reclamation Project In New Town,Macao

With the improvement of the country's comprehensive strength,the economies of various regions have also achieved rapid development,especially with the advent of the era of globalization,in order to face an increasingly fierce market competition environment,efficient road operations are essential.As one of the very important special economic zones in China,the reclamation construction in Macau has received more and more attention.Based on this,this article takes the reclamation project in the new city of Macau as the research object,and systematically analyzes the soft soil properties and treatment technology in the area.According to the existing data,it is recommended to use the plugged plastic drainage board + vacuum combined preloading method for the natural sludge in this filling area;for the backfill layer,the vibration treatment + vibration rolling method is used for the foundation treatment.Key elements and results achieved:(1)This paper first collects domestic and foreign relevant literature research data on the characteristics of soft soil in the reclamation area of Macau New City,puts forward the background and significance of this study,and presents this study based on data analysis and the actual situation of the reclamation project in Macau Method and content;(2)This part mainly introduces the theory and basic principles of the vacuum combined preloading preloading method,and analyzes the main points of its practical application in soft foundation treatment.The research in this article also provides the theory stand by;(3)This part analyzes the actual situation of the reclamation project in the new city of Macau,understands the hydrological conditions and engineering geology of the project,and further puts forward the difficulties in applying the vacuum combined preloading method,and explains the preloading The practical application process of the method in the reclamation project of the new city of Macau;(4)Based on the analysis and research in Chapter 3,a natural mud foundation treatment plan that complies with the characteristics of Macao's landfill area is proposed.At the same time,in-depth analysis and analysis of factors such as the operation of the entire actual project,its effectiveness,and results discuss.Secondly,analyze and study the relevant schemes of the natural silt foundation monitoring technology in the filling area,and use the monitoring data as the estimation of the final settlement;check whether the calculation method is correct,and conduct a detailed analysis of each impact parameter.Third,according to the characteristics of the natural silt foundation reinforcement project in the filling area,in order to ensure the quality of the drainage system and the sealing system,on-site sampling experiments and visual inspection must be performed according to the actual situation to ensure the project to proceed smoothly.This is also the focus of this thesis;At present,the vacuum combined preloading method has been widely used in seawall construction projects,which has very significant advantages.However,due to the influence of materials,geology and other factors,there are many difficult issues that need to be resolved in actual project construction.It is necessary to adapt to local conditions and adopt a reasonable and scientific construction method.Therefore,this paper starts a multi-angle and indepth study on the application of vacuum combined surcharge preloading method in the reclamation project of the Macau New Town.
