大连港香炉礁扩建的二号突堤码头及后方仓库,堆场等构筑物地基,全部用碎石土回填。设计要求回填后地基允许承载力[R]=15吨/米~2,沉降量 S允<10厘米,差异沉降量△S 允<1～2厘米,变形模量 E=300～500公斤/厘米~2,有效加固深度为10米。为了满足上述设计要求,确定用强夯法进行加固。在正式大而积加固之前先做了一组可行性试验。试验的目的在于寻找符合当地实际情况的强夯法施工工艺,并为今后用强夯
The foundations of the No.2 jetty and the rear warehouses, storage yards, etc. for the expansion of the Xiangluo Reef in Dalian Port are all backfilled with crushed rock. The design requires that the foundation after the backfilling allow the bearing capacity [R]=15 tons/meter~2, the settlement amount S is allowed to be less than 10 centimeters, the differential settlement amount △S is allowed to be less than 1 to 2 centimeters, the deformation modulus is E=300 to 500 kg/cm ~2, Effective reinforcement depth is 10 meters. In order to meet the above design requirements, it is determined that the reinforcement method is used. A set of feasibility tests was conducted before the formal large-scale consolidation. The purpose of the test is to find a strong construction method that complies with the actual conditions in the local area, and to use it for the future.
