采用14C同位素测试测定地层年代,通过工程地质综合确定河床冲刷深度,为建造河底隧道、桥梁提供必要的河床冲刷深度依据。本文介绍了杭州地铁1号线工程过江隧道通过14C同位素地质测年确定钱塘江河床冲刷深度的工程实例。
The 14C isotopic test is used to determine the age of the strata. The scouring depth of the riverbed is determined through comprehensive engineering geology. The river bed scouring depth is provided for the construction of river bottom tunnels and bridges. This paper introduces an example of determining the riverbed erosion depth of Qiantang River through the 14C isotope geologic dating in the cross-river tunnel of Hangzhou Metro Line 1 project.
