基槽泥沙淤积预报主要面向深中通道工程需求建设，基于数值模拟预报系统产生，主要列出了E1-E9共计9个管节沉放施工期间给出了基槽泥沙回淤厚度预报值。预报为沉管施工的决策以及施工组织提供了重要的支撑。从实际结果看，通过预报值准确给出了是否满足设计要求的判断，为施工提供了准确的依据。\n
数据时间范围为2020年6月至2021年4月件E1-E9管节沉放施工期间泥沙回淤预报数据，每次预报根据施工组织安排，预报碎石整平开始至沉管沉放施工完成之间的每日及累计泥沙淤积厚度。", "ds_source": "

The prediction of sediment deposition in the foundation trench is mainly aimed at the construction needs of deep and medium channel engineering. Based on the numerical simulation prediction system, it mainly lists the predicted thickness of sediment deposition in the foundation trench during the sinking construction period of 9 pipe sections E1-E9. The forecast provides important support for the decision-making and construction organization of immersed tube construction. From the actual results, it can be seen that the predicted values accurately provide a judgment on whether the design requirements are met, providing accurate basis for construction.\n
The data time range is from June 2020 to April 2021, during the sedimentation construction period of E1-E9 pipe sections. Each forecast is based on the construction organization arrangement, predicting the daily and cumulative sediment deposition thickness between the start of gravel leveling and the completion of sinking construction.
