課題 路基施工準備工作
教學目的 了解路基施工前要做的準備工作
重點難點 路基邊坡放樣的方法
教學內容、教學方法設計與時間分配:
第一章 路基施工的準備工作
第一節 概述
一、路基 施工的 重要性及施工方法
1 、重要性
路基施工的重要性是路基強度和穩定性的保證,不少公路病害的重要原因就是路基施工質量不良,引起交通阻塞,并消耗大量的養護和維修費用。
在公路建設中,路基土石方工程數量很大,各別公路路基工程要占全部公路的 65% ,某些重點路段往往是公路施工進度的關鍵。
2 、施工方法
主要有這么幾種:
a 人工施工 效率低、強度大、進度慢;
b 簡易機械化施工 生產效率較高,
c 水力機械化施工
d 機械化施工使用配套機械。
二、 路基施工的一般程序與內容
路基施工過程:

Preparation of subgrade construction issues
Objective To understand the foundation of teaching to do the preparatory work before construction
Setting out the key and difficult way roadbed slope
Teaching content, teaching methods and designs and time allocation:
Chapter Subgrade preparation
Section Overview
First, the importance of subgrade construction and construction method
1, the importance of
The importance of roadbed roadbed construction guarantees strength and stability, an important reason why many highway disease is poor construction quality of roadbed, causing traffic congestion, and consume a large amount of maintenance and repair costs.
In highway construction, the roadbed earthwork large number of individual highway subgrade to 65% of total roads, some of the key sections of highway construction is often the key to progress.
2, construction method
There are so few:
a low efficiency of artificial construction, strength, progress slow;
b simple mechanical construction of high production efficiency,
c Hydraulic Mechanical Construction
d the use of mechanized construction related machinery.
Second, the general procedures subgrade construction and content
Subgrade construction process:
