【Abstract】 Both of the new and old Yumatou drainage sluice are situated on soft soil foundation, though has been reinforced some times the old sluice which is a famous bad sluice in Hubei province still often occurs problems. In the character, We analyze the reason which cause the new sluice to occur some critical problem in the construction process. To solve the problems, cement mixing piles and jet-ground piles are used to strengthen the foundation; two sluices work together to reduce the sluice’s horizontal displacement. At last, we use the finite element process Plaxis to analyses the result of the reinforcement, from the calculation We can see the reinforcement is effected. In three years running, there has no new sink and unusual displacement appeared, so the reinforcement is successful.更多还原
