为解决城市洪涝诱发下穿隧道工程灾害风险的量化分析问题,分析了隧道工程洪涝的致灾、孕灾、承灾和减灾等因素,构建了城市下穿隧道洪涝风险评价模型。采用AHP-FCE模型评价法,选择某下穿隧道工程作为应用实例,借助AHP法获得了各层级指标的两两权重数据,依靠FCE法实现了各层级指标的评判得分。结果表明:1)防灾减灾能力指标对隧道工程洪涝灾害的影响程度最显著,承灾体脆弱性指标诱发隧道工程洪涝灾害的可能性最大,该下穿隧道在综合评价中获得“中等”风险等级,对施工质量和进度产生较大影响,需采取基本预防措施;2)提出了在城市下穿隧道洪涝风险治理方面应重点关注和改进的风险指标,实现了下穿隧道工程在洪涝情景下灾害风险的定量评级。

A prototype based on digital radio technology with associated open-loop Doppler signal processing techniques has been developed to measure a spacecraft's line-of-sight velocity. The prototype was tested in China's Chang'E-1 lunar mission relying on S-band telemetry signals transmitted by the sat-ellite,with results showing that the residuals had a RMS value of ～3 mm/s (1σ ) using 1-sec integration,which is consistent with the Chinese conventional USB (Unified S-Band) tracking system. Such preci-sion is mainly limited by the short-term stability of the atomic (e.g. rubidium) clock at the uplink ground station. It can also be improved with proper calibration to remove some effects of the transmission media (such as solar plasma,troposphere and ionosphere),and a longer integration time (e.g. down to 0.56 mm/s at 34 seconds) allowed by the spacecraft dynamics. The tracking accuracy can also be in-creased with differential methods that may effectively remove most of the long-term drifts and some of the short-term uncertainties of the uplink atomic clock,thereby further reducing the residuals to the 1 mm/s level. Our experimental tracking data have been used in orbit determination for Chang'E-1,while other applications (such as the upcoming YH-1 Mars orbiter) based on open-loop Doppler tracking will be initiated in the future. Successful application of the prototype to the Chang'E-1 mission in 2008 is believed to have great significance for China's future deep space exploration.

The tropopause has a complex structure and some interference information may exist in high-resolution global positioning system （GPS）/low earth-orbiting （LEO） radio occultation （RO） data. The position of the tropopause cannot be accurately determined using traditional cold point tropopause （CPT） and lapse rate tropopause （LRT） algorithms. In this paper, an integrative algorithm is developed to determinate tropopause parameters. The algorithm is applied to GPS/COSMIC RO data to obtain a global distribution of the height and temperature of the tropopause. This algorithm improves the utilization rate of GPS/LEO RO data by 30% compared with that from the traditional CPT method. The rationality and reliability of GPS/LEO RO data in probing the Earth＇s atmosphere are verified by our study of the tropopause using COSMIC data.
