厦门地区致密土体分段注浆技术试验研究

Sectional Grouting Technique Applicable for the Dense Soil Mass of Xiamen Area

厦门市机场路一期莲前西路下穿道及莲前—梧村山隧道位于莲前西路两侧的龙山山前台地和浦南工业区,建筑林立,不仅有密如蛛网的地下管线,而且车流量达每小时2 200辆,城市环境复杂;机场路在此段以浅埋、大跨隧道形式通过,隧道通过该路段时所遭遇到的水文地质、工程地质等问题异常复杂,设计中采用了注浆等措施。研究针对此复杂地质条件下的分段注浆技术,对本工程的实施具有重要意义。

Large-span shallow Xiamen airport road tunnel passes through a region with dense industrial plants and buildings on the surface, dense pipelines and underground facilities under ground surface and with complex hydrologic and engineering geology, thereupon sectional grouting was proposed in design and pending to be applied in construction.
