疏浚吹填高程预测系统

Elevation prediction system for dredging and reclamation

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。

The dredge and survey platform including a series of sampling,sampling preparation and vacuum preloading model test devices is designed and developed which can execute exploration,sampling and monitoring in reclamation soft soil. Taking a series of means including drilling and sampling, settlement monitoring, indoor soil test,model test and so on, combining physical index method, layerwise summation method, one-dimensional finite strain method of reclamation soil,and some settlement computation methods of in-situ soil and software calculation system,a software and hardware prediction system of reclamation elevation in reclamation area is formed.The system is used in a reclamation area behind 6#~ 8#berth in Binzhou port. The result shows that the reclamation elevation shall not be less than 8. 55 m if the foundation will be treated by vacuum preloading method and the elevation should reach 3. 5 m after treated.
