摘要：汉江航电枢纽上下游水位条件是设计重要参数。本文描述在内河如何收集、分析水文数据,考虑拟建码头上下游渠化整治设施不同建设时序的影响,采用多种方法确定拟建工程所需的设计水位,为复杂地形难以进行数学模型水位分析的工程设计提供了准确数据及方法建议。

摘要：文中主要以工程实例介绍利用港工大型船机的预制安装能力解决某临海大型泵房的施工,缩短了建设工期,减少了工程造价,取得了良好的经济效益,为以后类似深地下建筑工程的施工提供了借鉴。

摘要：文章所介绍的远程抄表系统是一种基于嵌入式ARM的系列技术,实现硬件终端设计,对电表数据进行采集,依靠GSM网络平台进行无线传输到上位机,方便工作人员对社区用电信息进行操作和管理。远程抄表系统势必会取代传统的人工抄表方式。

摘要：In actual production,deep coal mine roadways are often under typical static-dynamic coupling stress(SDCS)conditions with high ground stress and strong dynamic *** the increasing number of disasters and accidents induced by SDCS conditions,the safe and efficient production of coal mines is seriously ***,it is of great practical significance to study the deformation and failure characteristics of the roadway surrounding rock under *** this paper,the effects of different in-situ stress fields and dynamic load conditions on the surrounding rock are studied by numerical simulations,and the deformation and failure characteristics are *** to the simulation results,the horizontal stress,vertical stress and dynamic disturbance have a positive correlation with the plastic failure of the surrounding *** these factors,the influence of the dynamic disturbance is the most *** the same stress conditions,the extents of deformation and plastic failure of the roof and ribs are always greater than those of the *** effect of horizontal stresses on the roadway deformation is more notable than that of vertical *** results indicate that for the roadway under high-stress conditions,the in-situ stress test must be strengthened *** determining the magnitude of the in-situ stress,the location of the roadway should be reasonably arranged in the design to optimize the mining *** roadways that are strongly disturbed by dynamic loads,rock supports(rebar/cable bolts,steel set etc.)that are capable of maintaining their effectiveness without failure after certain dynamic loads are *** results of this study contribute to understanding the characteristics of the roadway deformation and failure under SDCS,and can be used to provide a basis for the support design and optimization under similar geological and geotechnical circumstances.
