Scenic Slope Retaining Contrast Effect Analysis

Abstract

As a natural and cultural heritage in the world,the slope of Longjing Road lies in the West Lake Scenic Area. However, this slope suffers from rain-wash, air-slake and later-on natural movements which cause collapse, thus the slope calls for engineering support. Yet the slopes we used to build are mainly aimed to construction engineering and highways particularly, that we must take their special locations into consideration. Their particularity demand that we should choose a certainly workable engineering support and design it in a way that delights people's eye at the meantime, therefore much more difficult work is to be done to meet it. Among those engineering support we know, retaining wall or anchor-type lattice beam is helpful in large-area virescence. Through rational design and beautification, it ensures the security and stability of the engineering support and meanwhile it helps with its pleasing outlook. By means of finite element strength reduction factor method, we analyze the stability of the slope on the Longjing Road with the finite element software and the effectiveness of retaining wall and anchor-type lattice beam. Also, through safety factors, displacement and destruction process, we compare the actual effectiveness of these two cases and work out some improvement measures. These results can serve as references in choosing engineering support schemes alike.Keywords-strength reduction of FEM; facter of security and stability; gravity retaining wall; anchor lattice beam;
