THE COMPREHENSIVE DESIGN ON SUBGRADE AND PAVEMENT FROM K12+600 TO K14+700 OF HANG RUI FREEWAY BETWEEN YUEYANG AND CHANGDE

ABSTRACT

According to the design information,demands of the design task instrument,the technical standards and specifications for freeway design published by the Ministry of Communications of China, the comprehensive design of freeway subgrade and pavement from K12+600 to K14+700 has been carried out based on the data of Hangrui freeway between Yueyang and Changde.
Our prime contents of the design project includes freeway route design, the design of pavement,the design of the bridges and culverts,translating an English article into Chinese,special study and compile a simple computer programme. According to route firsthand information that is offered ,we must keep the balance between the diging of filling out,maximun vertical slope,minimum vertical slope, the length of slope,high control point,etc. During designing the vertical section and combining the plane figure ,we design the cross section. According to the condition of climate district and remiting calculation water of quantity,set up drainage system which includes side ditch, intercepting ditch etc. Meanwhile, do block design of wall of soil calculate and protect engineering design , set up the reinforced retaining walls to go on, adopt plant turf to protect the slope ,etc. In high embankment highway section, shrink slope foot by building the retaining wall, reduce the filling, increase the slope stability; make use of BISHOP to follow the checking stability calculation. Do the design which has carried on the asphalt concrete road surface and design of the cement concrete road surface by giving volume of traffic definitely terms, according to the design principle of the road surface structure,select for different road surface structure layers of thickness and material then carry on structural design checking computations, and do scheme comparison..
Through graduation project,not only know of CAD,Hint 5.8 ,but also practice the ability to use office software like Word、Excel. The specialized knowledge and technologe have been comprehensively applied and improved ,and the perspective of solving problems had been enhanced.

Key words：road engineering; freeway; subgrade design; pavement design; comprehensive design
