Abstract:Safety is the focus of tunnel construction.During the period of construction of ZhongMaCha tunnel in Huang Yan highway expansion project, geological radar principle was adopted to predict the geological condition in advance and could master the geological condition in front of tunnel face accurately. Once harmful geological conditions was predicted, prevention and optimization of original design measures could be taken ahead of schedule to guarantee the construction safety.
