The completed project experienced the 1999 flood (with its water level of 28.89 m, ranking third in history). All the test data showed that the adopted comprehensive regulation measures were safe and reliable, achieving expected design results.
In light of the landslide phenomenon and erosion by Ruyuan River on K98+400~ K98+900 plot, as well as the geological construction characteristics of road cutting through high land, this paper introduces the comprehensive measures for the treatment of road cutting through high land under such complex environment and special stratum(high liquidlimit soil,richliquid coalbearing strata).
Based on conditions of the nature environment and the major problems in pollution in Shenyang,a series of the preventive strategies for noise,polluted air,filthy water and rubbish had been adopted. Strengthening ability of treating pollution,increasing green area,and controlling noise producing make the environment in Shenyang city better.
Based on the existing situation and recent practices and tasks planned for next decade, several ideas are given towards necessity, strategy and comprehesive measures to regulate the wandering reaches of the Lower Yellow River.
This paper analyses the geologic agent of sliding in loess region, the Northwest China and recommendes the methods for treating the Sliding. Great part of Northwest China, especially in the middle Yellow River valley, are covered with loess. The violent newtectonic movement in the later Pleistocene of Quaternary period resulted in earth crust rising, and rivers and gullies cuting down. So, the intercept of loess slope are increasing continuously, additionally, loess and the rock layer under it are strong pe...
The division of land for renovation and utilization in Ningxia is based on the distribution and composition of soil as well as the concerned condition and nature. The primary district is a natural geographic unit used in the renovation of the soil compositions with similar using way, the sudsidiary district is composed of consistent soil types in the primary district, this secondary uint is consisted of the soil with similar land renovation direction and conditions.The whole area of Ningxia Autonomous Regio...
