摘　　要：为改善软土地基沉降速率,加速软土地基的固结,在施工中采用袋装砂井及土工格栅预压排水固结法,并根据土工格栅的力学特性和施工中对地基稳定性的实时监测及时调整工程进度,在保证工程质量的前提下,确保了施工工期,为实施土工格栅施工方案积累了丰富的经验.To improve the soft ground sedimentation rate and accelerate the consolidation of soft ground, sand bags of wells and drainage geogrid preloading consolidation are used in the construction. In accordance with the mechanical properties of the geogrid, and the timely monitoring for the stability of foundation in construction, the construction progress is adjusted timely. To ensure the quality of the project and construction period,the plan has accumulated rich experience for the implementation of geogrid construction.
