【摘要】：设计研发了可在吹填泥塘中勘探取样、监测作业的疏浚勘测平台,包括一系列取样、制样、真空预压模型试验等装置。采取勘察取样、沉降监测、室内土工试验、模型试验等一系列手段,结合吹填土的物性指标法、分层总和法、一维有限应变法等计算方法,原位土沉降计算方法及软件计算系统,形成了吹填区吹填高程预测的软件和硬件系统。将吹填高程预测系统应用于滨州港海港港区6#~8#泊位后方吹填区的吹填高程预测,结果表明,当采用真空预压法处理吹填土地基时,要达到3.5 m的交地高程,场地的吹填高程不应小于8.55 m。
[Abstract]:A dredging survey platform which can be used for sampling and monitoring in dredged mud ponds is designed and developed, including a series of sampling, sample preparation, vacuum preloading model tests and other devices. Survey sampling and settlement monitoring are adopted. A series of methods, such as indoor geotechnical test, model test and so on, combined with physical property index method, stratified summation method, one-dimensional finite strain method, in-situ soil settlement calculation method and software calculation system. The software and hardware system for the height prediction of the dredging area is formed. The system is applied to the prediction of the height of the dredger in the backfill area of 6 #8# berths in the port area of Binzhou Port. The results show that the system can be used to predict the height of the dredger. When the filling foundation is treated by vacuum preloading method, the height of the ground crossing should reach 3.5 m and the height of the site should not be less than 8.55 m.
