摘要
海底土体的物理力学指标是反映工程地质环境的一项重要指标,获取海洋土体物理力学指标的最直接方法是静力触探原位测试技术。研究发现静力触探系统地锚机液压动力是单向功能,达不到螺旋地锚固定静力触探系统机架的技术要求,存在换向功能问题,提出了合理选择换向阀的几点建议。
In both the basic research and the engineering applications,it is needed to understand the marine engineering geo-environment.The physical and mechanical indexes of the seabed soils are the important ones reflecting the marine engineering geo-environment.The most direct way to obtain the physical and mechanical indexes of the seabed soils is to use the in-situ CPT technique.It is found that the hydraulic power of the anchor machine of the CPT System has a one-direction function.Such a function cannot meet the technical requirements of a fixed-static force system,indicating that the hydraulic system needs to have a direction-change function.This paper analyzes the problems about the direction reverse of the hydraulic power of the CPT system and puts forward some notices for selecting proper reversing valves.
