9、gineering or to evaluate and forecast the engineering geological problems that may occurred in the period of the service time(服务期)of the building.on this base,to give the effective engineering prevention methods.,the study about topography and landforms(地形地貌)the study about the fundamental engineeri

10、ng properties(physical and mechanics)of soils and rock(岩土工程性质)geological structure(地质构造),Geological Environment(Geological Condition)地质环境和地质条件的含义,4 the importance of GE(学习意义),hydrogeology(水文地质:地下水条件)the analyses of engineering geological problems(工程地质问题分析)the engineering investigation(工程勘察),5 Demand

11、s(requirements)(要求),1 to master the basic concept about EG 2 to comprehend the main geological problems occurred in engineering.knowing that how the problems happened,how can we prevent it.3 class discipline 4 finish the homework on time,Chapter 1 The basic information of earth 第一章 地球的基本知识,SECTION 1

12、-1 Inner structure of earth 第一节 地球的内部结构,This region is thin compared to the other layers in the Earth.It varies in thickness from 10km deep to 65km deep.The crust is made up of lighter rocks that float on top of the mantle.This layer includes the continents as well as the rock under the oceans.we ha

13、ve built many deep mines but NONE have yet reached the mantle!,The Crust(地壳),软流圈,岩石圈,上地慢,有关岩石圈(lithosphere),Structure of the Earths crust and top most layer of the upper mantle(上地慢).The lithosphere(岩石圈)consists of the oceanic crust,continental crust,and uppermost mantle.Beneath the lithosphereis the

14、 asthenosphere(软流圈).This layer,which is also part of the upper mantle,extends to a depth of about 200 kilometers.Sedimentary deposits are commonly found at the boundaries between the continental and oceanic crust.,This region lies under the crust and is approximately 2900km thick.The mantle is much

15、denser than the crust(which is why the crust floats on top)and has a texture much like tar.The rock in this region is rich in compounds made from iron,magnesium,and silicon which accounts for why it is denser than the crust.,The Mantle(地幔),This region is divided into two parts.The outer part is call

16、ed the Outer Core.It is about 2100km thick and made of liquid nickel and iron.The inner part is called the Inner Core and it is the real centre of the Earth.This part is about 2800km in diameter and is made of solid iron and nickel.,The Core:,SECTION 1-2 Plate Structure Theory 第二节 板块构造理论,1 Pacific P

17、late(太平洋板块)2 North American Plate(北美板块)3 South American Plate(南美板块)4 Eurasian Plate(欧亚板块)5 African Plate(非洲板块)6 Indo Australian Plate(澳印板块)7 Antarctic Plate(南极州板块),1 Pacific Plate 2 North American Plate3 South American Plate 4 Eurasian Plate5 African Plate 6 Indo Australian Plate7 Antarctic Plate,板块

18、构造理论,板块的形成(大陆漂移),海底扩张理论(Theory of Ocean Floor Spreading),海底扩张的证据(沉积物的年龄),海底扩张的结果(喜马拉雅山的形成),海沟的形成,岩石循环的概念,SECTION 1-3:The concept of Geological Action(function)第三节 地质作用的概念,2 The classification of the Geo.Action(地质作用分类)(1)outer-dynamics geological action(外动力地质作用)dynamic source is from the sun,gravity,

19、attraction force between sun and moon.Weathering(风化作用)the Rock is destroyed at the place where it was formed because of the outer dynamics.Erosion(剥蚀作用)Rock body 岩体 is separated from its mother rock(母岩)because of the water,wind,glacier.,Carrying(搬运作用)the process that rock is carried from one place t

20、o anther place.Because of Sedimentation(沉积作用)the process in which the carrying materials sink to the bottom of ground when the power of gravity of the materials is bigger than the carrying force.Rock-formation action(成岩作用)the process that the materials sunk to ground surface to become hard or solid

21、rock body.,Crust movement(地壳运动)B:Magmatism(magmatic activities)岩浆作用(magmatic intrusion and volcanic eruption)Earthquake(地震作用),(2)Inner-dynamics geological action(内动力地质作用)(the dynamics source is from earth,Metamorphism(变质作用)Because of the high pressure and or temperature,the rock is changed to a new kind of rock,This rock is called metamorphic rock.Every geological phenomena is the result of geological action.Including:A mineral,rock,Land shape(mountain,river,plain.)Tectonics,
