Abstract
Taking a building project as an example,the design and construction of H-beam+U-beam combined supporting structure were an-alyzed.The deformation characteristics and waterproof effect of foundation pit supporting structure were verified by monitoring technology,and the project cost and construction period were analyzed.The results show that when the foundation is excavated to the lateral deformation,the maximum horizontal displacement is 18 mm.The maximum deep horizontal displacement is 32.9 mm,an increase of 82.7%.During the con-struction process,the lower water level outside the pit remained basically stable,and the maximum drop depth of the water level was 45 cm.At the same time,the construction cost of HUW is 4.34 million yuan,and the construction period is only 2.5 months.In summary,HUW con-struction method has good water sealing effect,construction effect and remarkable economic efficiency.关键词
