黑河水库单薄山梁排水洞方案优选研究

黑河水库是解决西安市城市供水、农田灌溉及水力发电的大型水利水电工程。其左岸的单薄山梁既构成大坝坝肩岩体,蓄水后又成为一天然坝体。水库蓄水后的渗漏及渗透稳定性决定了水库能否安全高效的运行。黑河工程指挥部在防渗灌浆帷幕施工后,提出在帷幕下游增设单排排水洞。就此对排水洞方案进行了优选研究。     

静力稳定度对大地形降水影响的数值模拟研究

利用ARPS模式,通过调节过大地形山脉的湿大气静力稳定度进行敏感性试验,研究了湿大气静力稳定度对大地形降水的影响。结果表明,湿大气静力稳定度的改变影响了地形重力波的形成、维持和传播机制。当静力稳定度偏小时,地形重力波容易破碎,得不到有效维持;当静力稳定度偏大时,地形重力波又不易形成;仅当静力稳定度达到适合的强度时,地形重力波才能得到有效维持和传播。此外,垂直上升速度分布、辐合辐散运动及水汽的凝结输送等是影响大地形降水强度及分布状况的重要因素。

黑龙江省草帽山-基座山地区地球化学特征及成矿远景预测

黑龙江省草帽山-基座山地区位于大兴安岭中段华力西、燕山期铁、钨、银、金、钼、铜成矿带的北东端,呼玛县兴隆砂金矿区的南部。区内经历了漫长的沉积地层发育及多期次的强烈岩浆活动,分布有众多砂金矿床及岩金矿点,成矿条件较为优越。文章对区内1∶5万水系沉积物测量采集的样品分析数据进行了统计分析,将11种元素划分成Ag,Cu,Pb,Zn组合类型、W,Mo,Bi组合类型、As,Sb,Hg组合类型、Au组合类型,总结了区内地球化学特征及地质意义,并通过对各元素的平均值、变异系数、相关性及元素空间分布特征进行比较研究,认为Au元素含量高于全省丰度、变异系数为大(5.668),单元素异常强度高、浓度分带明显,为该区最主要的成矿元素,研究区是金成矿的有利地区。     

Utilization and sustainable development of island mountains in China

The island mountain utilization is a kind of mountain utilization. Although the islands cover little area, they can be used as the base of marine development. The sustainable development of island mountains is of significance to marine development. There are more than 6500 islands (including the South China Sea Islets) in China, and most of them are continental islands which are the extension of continental mountains extent towards sea. For this reason, there are many hills but few mountains, the area of hills makes up more than two thirds of the whole land area. In order to keep ecological balance of islands, the utilization of island hills and mountains should take exploitation of forests as the main to conserve water source and water-soil, and forests become an important factor in keeping ecological balance and sustainable development of islands. At the same time we should make good use of forests through setting up forest nature protecting area and forest parks and developing forest tourism. A part of research achievements of the project subsidized by National Natural Science Foundation (No. 49171026).

层次分析法在山地地质灾害危险性评价中的应用——以辽宁凌源地区为例

凌源市是辽西地区山地地质灾害危害较为严重的区域。在GIS技术支持下,选取地形、岩性、构造、降雨、道路、土地利用等6个因素作为评价指标,根据已发生的68个山地地质灾害点计算了各指标因子的敏感性,分别采用层次分析法、信息量法和统计量法确定了各指标的权重,利用因子叠置法对危险性进行了综合评价。结果表明层次分析法在该区山地地质灾害危险性评价中效果良好。该研究对相似地区山地地质灾害危险性区划具有一定的借鉴意义。     

太行山山前断裂带倾斜潮汐因子动态组合分析

利用Venedikov调和分析方法计算太行山山前断裂带地倾斜观测台站2002~2017年EW和NS分量的固体潮潮汐因子,获取潮汐因子异常与动态组合的3种特征量（扩容膨胀、剪切应变、介质的各向异性）时间序列,并分析其与太行山山前断裂带附近中等地震的关系。结果表明：1）断裂带上地倾斜潮汐因子受海潮负荷影响较小,潮汐因子并未因纬度的改变而表现出明显的规律性变化,其差异可能是因为受地壳横向不均匀变化的影响;2）地倾斜固体潮潮汐因子动态组合特征量与观测站点周边350 km范围内发生的ML4.0以上地震有较好的对应关系。
