摘要
上海采用先促淤、后圈围方式实施圈围工程时,部分促淤坝临近海堤,或成为海堤的一部分。随着海塘外部河势、滩势的变化,促淤坝与海塘间的反滤结构由于种种原因变形损坏,致使堤身(堤基)土方流失、大方脚或护坡塌陷、开裂等,危及海塘安全。为确保海塘的运行、防汛安全,海塘堤身土方防渗维修措施尤为重要。本文以高压旋喷桩为例,对防渗维修措施进行探讨,为今后解决海塘堤身土方防渗维修措施提供参考和借鉴。
After the implementation of sedimentation promotion and enclosure procedure for land recalmation project,a partial sedimentation promotion dam became a part of the seawall.Brought about soil loss and even spread footing damage,which increasingly raised seawall safety concerns.In this essay,the author makes a tentative study on the application of high pressure jet grouting,hoping to provide references for the seawall maintenance.
