在对山东省境内高速公路现行沉降观测实践的基础上,探讨适合于高速公路公路高填土路基沉降观测规范化的问题。提出沉降观测的精度指标、观测频率、水准测量等级及沉降观测测实施的具体要求,以期为准确实施沉降观测提供借鉴。
Based on the observation and practice of the current subsidence of expressways in Shandong Province, this paper discusses the problems that are suitable for the subsidence observation of highway subgrade filled with high-speed highways. The accuracy index, observation frequency, level measurement level and the specific requirements of settlement observation observation are put forward in order to provide reference for the accurate implementation of settlement observation.
