泡沫轻质土在工程建设领域中的新应用

论述了泡沫轻质土在梁桥拼宽及加固、拱桥荷载置换改造、轻型桥台台背回填、市政管道基坑回填和减少其他工程对轨道磁浮桥梁桩基的影响等工程领域中的新应用。实践证明:泡沫轻质土的轻质性、自立性、高强性、流动性等特性在工程建设领域具有无可替代的优势，不仅在上述领域的应用中取得了很好的效果，还可以被推广应用至城市人防等有积水或有毒气体的空腔回填等更多新兴领域。

New Uses of Foam Lightweight Soil in the Field of Engineering Construction

The new uses of foam lightweight soil in the fields of bridge widening and strengthening, replacement and reconstruction for bearing load of arched bridge, lightweight abutment backfill, foundation pit backfill in municipal pipeline, and reducing effect of other works on bridge pile foundation of maglev project, was described herein. Practice has proven that foam lightweight soil is of lightness, independence, high rigidity and flowability, thus has irreplaceable advantages in the field of engineering construction; it not only works well in the above mentioned areas, but also extends to some emerging fields, such as civil defense engineering of cavity backfilling with standing water or poisonous gas.
