Underground structure engineering in areas with high underground water level, such as tunnels, basements, underground or semi-underground pools and the like, needs to be specially designed for resisting floating under the condition that the self weight of the structure is not enough to resist the buoyancy of underground water.
The general structure itself has several types of anti-floating measures: increasing the weight to resist the buoyancy. And secondly, resisting buoyancy by using uplift piles. Anchoring with anchor rod to resist buoyancy. The above several commonly used methods have their own disadvantages and limitations: increasing the weight is usually an increase in the thickness of the structure, or an increase in the weight internally, which is mostly uneconomical; the adoption of the uplift pile or the anchor rod is realized by utilizing the frictional resistance or the anchoring force formed by embedding the uplift pile or the anchor rod into a rock stratum, so that the condition that the rock stratum is arranged on the shallow earth surface is needed, and the method has great limitation on the regions with poor shallow soil quality.
However, a great number of coastal cities in China belong to soft soil areas, rock strata are basically absent within 50 meters of the ground surface, the underground water level is high, underground water appears at 0.5-1.5 meters of the ground surface, the buoyancy is high, and special anti-floating design is required.
At present, the traditional construction process is adopted in the construction of the anti-floating anchor rod, and the reinforcing steel bars of the anti-floating anchor rod are placed after hole forming, but the traditional anti-floating anchor rod is not high in structural strength and poor in anti-floating performance and is not suitable for complex construction environments.
