PRELIMINARY STUDY ON THE FLOODING AND DROUGHT CLAMITY DURING PAST 1500 YEARS IN THE HAI′AN REGION，JIANGSU PROVINCE   总被引：1，自引：0，他引：1

Collection and arrangement of the historical records of climatic changes and environment evolution,espectial-lyin the aspect of calamities,are made on the history documents of past 1500 years about Haiˊan region,Jiangsu Province.There existed two obvious flooding-drought frequently-occurring periods:one was from 1550 AD to 1850 AD and another was 100 AD to 1200AD.The period of 1550 AD to1850 AD is interrupted by two relatively arid and cold climatic periods:one was from 1630 AD to 1700 AD and another was 1750 AD to 1820 AD.The main characteristic of the calamity periods is that they occurred by turns,and sometimes,both drought and flooding occurred in the same year.The instability of the climatic changes in the Little Ice Age may be the main reason of the frequently-occurring flooding and drought in Haiˊan region.Research results also show that the frequently-occurring periods of flooding and drought is in close relationship with the solar activity,and therefore,occurrence of the flooding and drought may be in relation with the intensity of the solar activity.This hypothesis may need further study in the future.  相似文献

雷朝进 《浙江国土资源》2005,(7):64-64

6月18日以来，景宁县普降大暴雨，洪水；中毁道路、房屋、桥梁、电力通讯设备等，造成重大经济损失。截止23日统计，这次洪灾共引发滑坡、崩塌、泥石流等各类地质灾害106起。在这次抗洪中，县国土资源局早准备、早部署，有效地组织抗洪，全局出动抗洪23次59人。县乡村各级干部战斗在抗洪一线，特别是负责地质灾害隐患点的乡镇村干部和国土资源所工作人员高度重视，紧急撤离63个隐患点中的1503人，  相似文献   

某滑坡稳定分析及处理方案探讨   总被引：6，自引：0，他引：6  

毛新虎 《长安大学学报(地球科学版)》2003,25(2):22-26

滑坡属于不良地质现象，是斜坡上的部分岩体和土体在自然或人为因素的影响下沿某一明显的界面发生剪切破坏向坡下运动的现象。当高速公路不得不通过某一滑坡时，对其稳定性进行分析和整治设计就显得尤为重要。以祁临高速公路灵石至霍州段窑深沟大桥东南窑深沟滑坡为实例，根据勘察资料，利用岩土力学知识，在公路修好后并运行的情况下，计算出了其稳定系数和推滑力，又以材料力学、结构力学等力学理论为基础，设计出抗滑桩和锚索抗滑桩等两种整治方案，经验证，效果良好。  相似文献   

DISASTER ANALYSIS AND COUNTERMEASURES OF LAND SUBSIDENCE CAUSED BY COAL CUTTING IN CHINA     

YANGYong-liang SHITong-guang JLANGLU-guang LIYue 《中国地理科学(英文版)》2003,13(2):130-133

In recent years, many coal-producing countries have paid great attention to the land subsidence causedby coal cutting. In China, because of the dense population in coalfield areas, the land subsidence hazard is more seri-ous. After a brief analysis on the mechanism of land subsidence, this paper gives a comprehensive and systematical ac-count on all kinds of hazards caused by the land subsidence in China. The study shows that land subsidence has endan-gered land, buildings, traffic and communication lines, dykes and dams. It also causes damage to ecological and socialenvironment. In order to lessen the hazard of land subsidence, preventive measures should be taken to reduce the col-lapse amount, such as extraction with stowing, banded mining system, succession and coordination mining system, orhigh-pressure mudflow between rock strata. Measures of reinforcing or moving certain buildings should also be taken toreduce the destructive degree. In order to harness the subsidence land and bring them under control for fanning, mea-sures should be taken such as filling with spoil or fine breeze, excavating the deeper and covering the shallower land.  相似文献
