三河隧道进口段临建工程施工场地因地势陡峭,需要进行大量开挖山体,才能得到所需要的面积。其边坡高度普遍较大,为确保山体稳定及满足施工场地需要,边坡防护必须进行重新设计并对已开挖坡面进行整改完善,以达到稳定边坡,满足施工需要的目的。 Due to the steep terrain of the temporary construction site of Sanhe Tunnel’s entry section, a large amount of excavation of the mountain body is required in order to obtain the required area. The slope height is generally large. In order to ensure the stability of the mountain and meet the needs of the construction site, the slope protection must be redesigned and rectified and improved on the excavated slope so as to achieve the purpose of stabilizing the slope and meeting the construction needs.
