软基处理下吹砂回填量Matlab细化计算方法

吹砂回填普遍存在于港口工程、岛隧工程等相关建设中，具有工程量大、运输距离远、成本高昂的特点。为尽可能在吹填砂计算中获取准确的数字，介绍了基于多波束测量数据和Matlab编程的吹填方量的细化计算方法。根据振冲和排水板的地基处理效果，反推吹填砂固结和堆载影响，精确计算吹填砂量并给出吹填交工高程。在巴拿马阿马多尔邮轮码头项目实践中，精确计算的吹填砂量较传统的计算方法节省约7万m3的吹填量。

Matlab refinement calculation method of reclamation sand volume considering ground improvement

Reclamation is applied in port construction, artificial island and so on, which has the characteristics of large engineering volume, long transportation distance and high cost.In order to obtain accurate figures in reclamation sand volume calculation as far as possible, the detailed calculation method of reclamation sand volume based on multi-beam measurement data and Matlab programming is introduced.According to the foundation treatment effect of vibroflotation and drainage board, the consolidation and surcharge effects of dredger fill sand are inversely deduced, thus the amount of dredger fill sand is accurately calculated and the accurate handover elevation of reclamation fill is given.In the practice of Panama Amador cruise terminal project, the amount of reclamation accurately calculated can save about 70, 000 m3 compared with the traditional calculation method.
