污水排海管线廊道位置的优选步骤与方法

海洋环境地质条件的调查研究是污水排海管道路线优选过程中一个十分重要的环节，因此进行科学的调查研究是十分必要的。本文通过介绍薛家岛污水排海工程中水下管道路线优选过程，以及所做的海洋工程地质调查研究，试阐述污水排海管线廊道位置优选的调查研究方法。其过程可分为：（１）大范围普查和稳定性研究；（２）小范围详查和稳定性研究；（３）管线位置的确定。

A Procedure and Methods for Determining the Optimal Route of Submarine Waste pipeline

Optimal route decision of submarine waste pipeline is based on marine geotechnical exploration. A case study in which, route decision procedure of submarine waste pipeline in the Xuejiadao area, is introduced in this paper. From the case, it is concluded that the procedure can be divided into three stages. Firstly, reconnaissance survey and geological research in the large area; Secondly, detailed investigation and geological research in the appointed area; Thirdly, analysis and decision of the pipeline location. A high resolution acoustic survey and bottom sampling were used to reveal the features and property of submarinc sediment. This study into the slope stability is an important aspect of the program.
