为了准确地对山岭隧道建设工程中的塌方进行风险评估,基于最大熵原理和属性区间识别理论建立了山岭隧道塌方风险评价模型。具体工作流程是:选取围岩级别、地下水状况、岩体完整程度等7个主要因素作为隧道塌方风险评价指标,制定相应的属性区间评价指标分级标准;采用综合赋权法进行隧道塌方风险指标的权重分析;利用均化系数和基于最大熵原理的属性区间识别理论来确定属性测度区间;应用置信度准则对隧道塌方风险性进行属性识别,确定塌方风险性等级;运用评分准则对塌方风险进行评分,根据分值对两次或多次所属相同级别的风险进行比较排序。利用建立的评价模型与属性识别模型以及模糊层次分析法进行对比,结果吻合性较好。将该模型应用到实际工程中对塌方风险进行评估,并与现场情况作对比,证明了该模型的适用性和可行性。

本文从单井相、沉积微相及沉积相与油层的关系等方面对下寺湾油田张43井区长6油层组沉积特征进行了研究,认为研究区沉积相类型主要为三角洲相,沉积微相类型为水下分流河道及其侧缘和水下天然堤。该区优质储层主要分布在水下分流河道与其侧缘,其中水下分流河道较多,储层多受沉积微相控制,少数不能连成片的受沉积相和成岩作用共同的影响。

To investigate the cause of fine particulate matter(particles with an aerodynamic diameter less than 2.5 um,PM2.5) pollution in the heating season in the North China Plain(specifically Beijing,Tianjin,and Langfang),water-soluble ions and carbonaceous components in PM2.5were simultaneously measured by online instruments with 1-hr resolution,from November 15,2016 to march 15,*** results showed extreme severity of PM2.5 pollution on a regional *** inorganic ions(SNA,i.e.,NO3-+So42+NH4+) dominated the water-soluble ions,accounting for 30%-40% of PM2.5,while the total carbon(TC,i.e.,OC+EC) contributed to 26.5%-30.1% of PM2.5 IN the three *** were mainly responsible for the increasing PM2.5 pollution compared with organic matter(OM).NO3-was the most abundant species among water-soluble ions,but SO42- played a much more important role in driving the elevated PM2.5 *** relative humidity(RH) and its precursor SO2 were the key factors affecting the formation of *** reactions dominated the formation of nitrate which was mainly limited by HNO3 in ammonia-rich *** formation and regional transport from the heavily polluted region promoted the growth of PM2.5 concentrations in the formation stage of PM2.5 pollution in Beijing and *** transport or local emissions,along with secondary formation,made great contributions to the PM2.5 pollution in the evolution stage of PM2.5 pollution in Beijing and *** favourable meteorological conditions and regional transport from a relatively clean region both favored the diffusion of pollutants in all three cities.
