摘要
分析了软土、湿地、滩涂地区特殊地理环境对测量控制点的影响;主要探讨了此类地区控制点标志的设计、施工。借助于建筑桩基技术和道桥施工方法,首次成功实现了某三角洲湿地滩涂地区统一布网。几年来,结合滩涂湿地测量、海岸防护和滩涂开发工程对部分控制点进行了初步检测,给出了部分检测数据。应用和检测均表明:桩基标石可较好地解决软土、湿地、滩涂地区控制点布设难题,显著提高软土海岸地区测量控制点标志的稳固性,从而延长控制网的可使用期。
In this paper, the characteristic in region of soft soil, moist soil and beach land are described, and their influence on surveying control points is analyzed, Mainly, a method is presented for constructing a surveying control point with a pile-foundation. With the method, an integral control network all over the whole delta of a fiver is successfully created for the first time, The network has been used and checked in beach protectdevelopment engineering in several years, It shows us that constructing a surveying control point with a pilefoundation is a good method for improving the stabilization of surveying control point greatly, and networks in region of soft soil, moist soil and beach land will be used for long time than ever.
