塘沽网球馆室内地面不均匀沉降原因分析及纠偏技术的研究

STUDY ON UNEVEN SETTLEMENT AND RECTIFICATION TECHNOLOGY OF TANGGU TENNIS STADIUM

通过分析塘沽网球馆室内地面不均匀沉陷产生的原因,介绍了在不损坏原场地地面的前提下对地面进行纠偏的方法,该方法综合运用了压载法、掏土法和射水取土法,成功地实施了纠偏,使该场馆地面基本满足了使用要求。通过本例说明地面纠偏是一个动态的过程,是在纠偏的过程中不断修改方案、实施方案、调整方案直至达到目标的过程。该工程的成功经验可以为今后大面积室内地面不均匀沉陷的纠偏工作提供借鉴。

This paper analysis of causes of differential settlement of an tennis stadium, and presents the method of rectifying the tilt without damage the stadium ground, which integrates compression load method, digging soil holes method and taking soil by water jetting method. The tilt was rectified successfully and the stadium ground basically met the special requirements on smoothness. It is pointed out that rectifying the tilt is a dynamic process and a process that includes formulating scheme, implementation scheme and adjustment scheme and finally making it out. The successful experience of this project has a certain reference value for uneven settlement treatment of big-area stadium ground.
