Abstract:
Rubber water stops are the most commonly used waterproofing measure at tunnel joints. However, in engineering practice, rubber water stops are often damaged by excessive differential settlement at tunnel joints, which in turn causes water leakage diseases. The ABAQUS software numerical simulation method was used to analyze the deformation adaptability of the rubber water stop, and the cross-section form was optimized. An elliptical middle-hole rubber water stop suitable for larger differential settlement was proposed. The results show that the differential settlement at the joint is the key factor determining whether the rubber water stop can achieve the predetermined waterproof effect. The circular hole rubber water stops commonly used in the project can withstand the maximum differential settlement of about 30 mm. The long half-axis of the elliptical medium-hole rubber water stop can reduce the tensile and shear stress of the water stop under differential settlement, and can convert the tension of the water stop into the sliding close to the concrete surface, which effectively improves the deformation adaptability of the water stop. The product of the ratio of the area of the hole in the rubber water stop and the ratio of the length of the long half axis to the length of the short half axis can effectively characterize the deformation adaptability of the rubber water stop, and its value has a linear relationship with the maximum differential settlement that the elliptical hole rubber water stop can withstand. The reasonable value of the area ratio of the elliptical hole is 0.3-0.4, and the reasonable value of the length ratio of the long half axis and the short half axis is 1-2.5.
