摘要: 鉴于海绵城市建设中海绵设施效能监测不足、手段复杂且精度低的问题,将光纤传感技术应用于海绵城市透水铺装中,以光纤光栅温度传感器为监测手段,以外界量改变引发透水面层上下铺设传感器输出波长信号变化为基本原理,得出雨水渗透速率,并以此为核心指标。以湖北省暴雨资料为基础,模拟不同重现期(1,5,10,50,100 a)下不同透水铺装对雨水径流量的削减实验,结合实验数据,建立了雨水渗透速度与透水铺装径流量削减指标的线性拟合关系。结果表明:渗透速度与径流量削减率、产流时刻均有较好相关性(R2>0.93、R2>0.92)。该技术在鄂西地区高铁站成功应用,证明利用渗透速率监测产流时刻与径流量削减率是可行的。Abstract: In view of the lack of monitoring of the effectiveness of various sponge facilities, complex means and low accuracy in the construction of sponge cities, by applying fiber-optic sensing technology to sponge urban permeable paving, the optical fiber grating temperature sensors were used as the monitoring method and the basic principle was the change in the output signal of the sensor on the water-permeable surface layer caused by changes in external quantity. With the rainwater penetration rate obtained and used as the core index, based on rainstorm data of Hubei, the simulation of different permeable pavements on rainwater runoff reduction was conducted under different recurring periods (1a, 5a, 10a, 50a, 100a). Based on the experimental data, the linear fitting relationships between the permeability of rainwater in the permeable surface layer and the permeable pavement to runoff reduction indicators were established. The results showed that there was a good correlation between the infiltration speed and the runoff reduction rate and the time of the runoff (R2>0.93、R2>0.92).The application of the system in high-speed railway stations in western Hubei area successfully proved the feasibility of using infiltration rate to monitor the time of runoff and runoff reduction rate.
