软土地基地区高程基准建设探讨

Research on the Height Datum Construction in the Soft Soil Foundation Area

在宁波市高程控制点数据基础上,通过对各类别控制点不同沉降情况的研究分析,同时结合建设费用、应用范围等多项综合指标,提出类似宁波软土地基地区建设、维护、使用高程测绘基准的一些建议和思路,为城市规划、施工建设、社会经济发展提供有效可靠的测绘数据保障。

In this paper,based on the elevation control point data of Ningbo City,we researched the different subsidence of all kinds of elevation control points at first.And then,combining with the comprehensive index,such as the construction cost,application scope and so on,we gave some suggestions andideas of construction,maintenance and use elevation surveying datum in the soft soil foundation.This study can provide effective and reliable surveying and mapping data security for urban planning,construction,social and economic development.
