LS和TLS方法在高程拟合技术中的应用研究

传统的GPS高程拟合技术使用最小二乘方法对拟合模型进行平差计算,其模型的系数矩阵大多由高程点的平面坐标组成,而平面坐标也是施测GPS得到的观测值,因此也存在观测误差,最小二乘方法并没有考虑系数矩阵的误差,显然与实际情况存在偏差。为解决此问题,本文提出了总体最小二乘方法,并使用该方法对某长江大桥数据进行试验,分析和对比,验证总体最小二乘方法对于提高高程拟合精度的有效性。

合肥地区上更新统黏土中节理的几何学特征与构造意义

城市大规模工程建设揭露了蕴含在土层中的丰富变形信息,调查发现合肥地区上更新统黏土中发育有数量众多的节理,节理成组产出,呈现不同交切、配套关系。通过对大量的调查数据进行统计分析,并绘制各调查点的节理玫瑰花图,将研究区内节理发育与断层分布逐一对比分析,结果显示合肥地区上更新统黏土中广泛发育的节理产状与场地附近的主要断层产状有关。走向玫瑰花图显示节理优势分布方位与场地附近主要断层走向近似一致;如果场地附近有多条断层交汇,土层中节理有以北西向较为优势的特征。

郯庐断裂带赤山段中晚更新世之交的史前地震遗迹

Chishan is located in Sixian County of Anhui Province, and the west branch fault of Tancheng-Lujiang fault zone passes through here. According to previous research, the Chishan segment of Tancheng-Lujiang fault zone has been obviously active since the Quaternary. Trenches excavated perpendicular to the Chishan segment for this study have revealed many prehistoric earthquake ruins-the multi-phase reverse faulting colluvial wedge, which is represented as the western brick-red sandstone of the late Cretaceous or maize gravel stratum of the mid Pleistocene of the hanging wall of the fault overlapping eastward the mid-late Pleistocene brown clay. In the base of the wedges, steep NW-dipping faults were found, and the steep fault planes turned upward to gently dipping collapse planes. As revealed by the trenches, the connection line of the breaking points strikes NNE in general. Heaving landforms are preserved at most parts of the tailing edge of the hanging wall where the fault passes through, and some EW-trending gullies were offset by right-lateral faulting. The two walls of several trenches have consistently shown that the collapse of traces have been pushed by a west-to-east force. Among them, Tc1~Tc4 show that the brick red limestone(K2)overthrust and collapsed on the yellow-brown clay containing ferro-manganese nodules (Q2-3P); Tc5 reveals that the yellowish-white gravel (Q2P) and the sandstone (K2) and overthrust and collapsed on the aforementioned clay. Reverse faulting colluvial wedges are found on both walls of each of the 8 trenches, but the number of wedges revealed in different trenches is different: there is 1 wedge, and 2 wedges in Tc1 and Tc3. 3 wedges in Tc2, Tc4 and Tc5, and in individual trenches, few wedges are revealed. This may be related to the trench’s location, depth and height of the remaining denudation. From the analysis of the trenches and the thermoluminescence dating results, we can preliminarily conclude that multiple large-scale reverse faulting stick events have taken place on the Chishan segment of the Tancheng-Lujiang fault zone during the mid-late Pleistocene, that is to say, many pre-historic strong earthquakes have occurred.     

赤泥中氟迁移转化的影响因素分析

为了研究赤泥中氟向下运移过程中的影响因素,根据堆场周围的水文地质条件,设计了7组动态淋溶试验,并对试验数据进行了灰色关联度分析。结果表明,排放7天后的赤泥其表面下700 mm处的温度仍达78℃,而刚排放到堆场的冲灰水温度更高,可达87.5℃,高温赤泥和冲灰水有利于氟的迁移;赤泥的pH值为10.29～11.83,浸出液的pH值为12.00～13.20,碱性很大,致使氟易随水迁移;赤泥的其它污染组分,如总硬度、Cl-、SO42-、K+、Na+、Ca2+、Mg2+,均对氟的迁移有一定的影响,且Na+、SO42-和Ca2+为主要控制因素,即溶液中Na+、SO42-、Ca2+含量越高,赤泥中的F-离子越易淋出。      

乡镇规划编制方法初探

我国从1999年开始实行土地用途管制制度,土地利用总体规划编制和实施的历史不长,规划理论体系仍在逐步完善的过程中。由于全国各地乡镇具体情况千差万别,乡镇规划作为我国五级规划体系中重要的组成部分,编制的理论和技术却往往被忽视。相当长的时期内,我国大多数人口仍居住在乡     

基于虚拟路由冗余协议和双向转发检测的基层气象通信网络设计和实现

目前陕西省气象宽带通信网省、市、县3级连接中,区县局出口是以单台路由器连接双运营商线路接入市局,这一架构造成明显的路由器单点故障风险,同时也不能有效解决台站各业务之间带宽竞争的问题。据此改造市-县级网络拓扑,在区县局出口部署双路由器,分别对接电信、广电运营商线路。启用VRRP(虚拟路由冗余协议),并配置VRRP的负载分担模式,对台站业务根据带宽消耗和时效性高低进行分流传输,在链路冗余的基础上实现了双机热备和负载均衡。同时配置BFD(双向转发检测协议)和VRRP联动,通过BFD监控VRRP路由器的上行链路状态,实现主备路由器的快速切换。经过在西安市多个区县局的广域网建设实践和一年多的业务运行,收到了预期的效果,方案可为同级气象部门提供参考。
