完形填空

Any car accident is frightening, but an accident in which your vehicle is thrown into the water, with you trapped inside, is absolutely terrifying.__小题1:__ However, most deaths result from panic, without a plan or understanding what is happening to the car in the water.By adopting a brace(支撑) position, acting decisively and getting out fast,you can save yourself from a sinking vehicle.

Brace yourself for impact(撞击力).As soon as you're aware that you're going off the road and into a body of water,adopt a brace position.The impact could set off the airbag system in your vehicle,so you should place both hands on the steering wheel in the  “ten and two” position.

Undo your seatbelt.__小题2:__ Unbuckle the children,starting with the oldest first.Forget the cellphone call.Your car isn't going to wait for you to make the call.

_小题3:_ Leave the door alone at this stage and concentrate on the window.A car's electrical system should work for up to three minutes in water,so try the method of opening it electronically first.Many people don't think about the window as an escape option either because of panic or misinformation about doors and sinking.

Break the window.If you aren't able to open the window,or it only opens halfway,you'll need to break it with an object or your foot.It may feel counter­intuitive(有悖常理的) to let water into the car._小题4:__

Escape when the car has equalized.If it has reached the dramatic stage where the car cabin has been filled with water and it has become balanced,you must move quickly and effectively to ensure your survival._小题5:__ While there is still air in the car,take slow,deep breaths and focus on what you're doing.

A.Open the window as soon as you hit the water.

B.Surviving a sinking car is not as difficult as you think.

C.It takes 60 to 120 seconds for a car to fill up with water usually.

D.Such accidents are particularly dangerous to the risk of drowning.E.In conclusion,if you know what to do in the water,you will be safe.

F.This is the first thing to attend to,yet it often gets forgotten in the panic.

G.But the sooner the window is open,the sooner you can escape directly through it.

1.______ 2.______ 3.______ 4.______ 5.______

问答题 简答题

案例分析一背景资料:

某施工单位承接了9.82km的三级公路路基施工,路基宽8.5m,设计车速40km/h。其中K3+100-K3+420为路堤段,K3+280处设有1-2.5mx2m的盖板涵,涵洞长度17.62m,涵底坡度1%,K3+280的路基设计标高为206.307m。涵洞构造示意图如下:

K3+280涵洞构造示意图:

工程开工前,在业主支持下,由设计单位向施工单位交接了交点桩,水准点桩,设计文件中提供用于中统放样的资料只有“直线,曲线及转角度”,施工单位备有全站仪,自动水准仪等常规测量仪器。

涵洞施工与涵洞前后路堤T1区,T2区的建筑同时进行,T1区,T2区按图示坡度分层填筑。涵洞施工中,施工单位首先进行了涵洞中心桩号,涵轴线的放样,涵洞基坑开挖平面尺寸按17.62mx3.8m放样,基坑开挖严格按放样尺寸采用人工垂直向下开挖至基底设计标高。在对基底进行处理并通过验收后,开始基础施工。

涵洞完工后,在涵洞砌体砂浆或混泥土强度达到设计强度的70%时,进行涵洞两侧及顶面填土,建筑顺序为T3区—T4区—T5区,建筑方法采用人工配合小型机械夯填密实。

问题:

1.按涵顶填土厚度划分,指出该涵洞类型,并说明理由。

2.写出可用于本路曲线段中线放样的两种方法。

3.写出涵洞构造示意图中A,B,C结构的名称。

4.找出涵洞基坑施工中的错误,并说明理由。

5.改正填筑施工中的错误。
