This paper records the seasonal incidence of shrimps, sprats and herrings, the most abundant nektonic species, off West Thurrock in the Thames estuary during 1967–70. It also deals with their age classes and their diet. The object of monitoring the shrimp fish fauna is to establish a quantitative base line against which the effects of future developments for the river, such as the erection of a barrier, can ultimately be measured. It can also serve as an index to the effects of the strike of public employees of sewage plants on the state of the river, and monitoring for this purpose continues and will be reported later. 相似文献

对现浇钢筋混凝土建筑结构施工期间,模板支撑系统架设中可能存在的薄弱层对施工荷载分布的影响,提出了简化分析方法,并用工程实测结果进行了验证,表明模型计算结果的正确性.分析表明,模板支撑薄弱层将导致模板支撑薄弱层的上部楼板承担的施工荷载增大,而模板支撑薄弱层下部楼板承担的施工荷载减小;实测表明,模板支撑薄弱层上的楼板承担的施工荷载同比增大约4.3%,薄弱层下的楼板承担的施工荷载减小约3.9%.施工期间应避免模板支撑薄弱层的出现,以防模板支撑薄弱层可能带来的风险. 相似文献
