浅谈挡土墙的外观控制(国外英文资料) Talk about the line control of the retaining wall Zheng Li wu Abstract: over the years, Yang, exterior oblique earth-retaining wall always has some flaws, including the construction technology and construction measure are played a key role, how to control, in this paper, the back inclined type retaining wall the appearance of the problem in the construction process of some views for the individual. Keywords: high road elevation retaining wall appearance control 1. Introduction With the development of highway construction in China, especially the rapid development of high-grade highway. Retaining wall is widely used in highway construction of a retaining protective structures, especially the oblique type retaining wall, has become the dominant region of guizhou highway retaining protection. Because, the subgrade slope excavation retaining wall, wall of upward inclined type retaining wall back easily combined with excavation slope, can reduce the quantities of the conditions, protect the stability of the slope; To fill project, under the condition of terrain, terrain and construction permit, elevated diagonal type back earth pressure of retaining wall is small, to obtain more economic wall body section, at the same time also can shorten the construction period. Engineering overview Travelling with three standard in guizhou qiannan changshun, the period of this contract is located in the karst landforms, across the 9.347 km long, high fill embankment dig section is more, the total amount of excavation is 1658761 m? The total amount is 1989122m? . There are ten block walls in the line and 477.95 m in total, both of which are leaning against the earth wall. Causes and hazards of cosmetic defects With the development of the project, the appearance is not the whole of upward inclined type retaining wall, concrete surface voids, pits and matt surface, linear bad, wrong, offset, the cross section vertical to a sequence of ills such as folding line gradual
