Research results:It is necessary to establish the GPS base-station network for setting up the precise.
研究结果:对于高速铁路精测网的建设,GPS基站网的建立是必要的,便于精测网的复测和维护;对于线路通过区域地面沉降严重且不够均匀的地区,埋设深埋水准点是必要的;对于铁路沿线缺少足够稳定可靠的国家一、二等水准点和基岩点,埋设少量的基岩点也是必要的;成点对布置的基桩控制网CPIII,通过使用具有自动量测功能且测角精度优于1s的全站仪进行观测,采用合适的平差方法,相邻点位精度可以达到1mm,满足铺板要求。

测风站
station for air measurement
CefengZhon测风站(station for air measurement)测定风速的专用设施。矿井的总进、回风道,以及各翼、各阶段和各主要作业区的进、回风道,均应设置测风站,并挂记录牌,注明测风站的编号。测风站应符合四点要求:(l)选在巷道的直线段,前后10一15m范围内巷道断面无明显变化。(2)长度不小于4m,其断面积不小于4m2.断面内无障碍物。(3)周壁光滑平整,木支护的巷道需钉以木板,不支护的巷道壁面上应涂抹水泥砂浆。(4)测风站边壁与巷道边壁之间的空隙应严密堵塞,防止漏风。 (染昌才)
