摘 要:高速公路桥台由于高填方和土质不良等原因经常出现桥台路基沉降问题,导致一系列桥梁病害严重影响高速公路的运行安全和行车舒适度。为了较好地解决桥台基础沉降这一问题,高压旋喷桩技术较传统的静力注浆技术在加固质量和适用范围方面有很大的优势,另外高压旋喷桩具有施工便捷、施工速度快、对周边扰动小等特性,本文以工程成功实践案例,详细介绍了高压旋喷桩技术的应用情况,达到了预期的效果,为同类型施工项目提供了重要的参考价值。The abutment subgrade settlement of expressway abutment often occurs due to high fill and poor soil quality,which leads to a series of bridge diseases and seriously affects the safety and comfort of expressway operation.In order to better solve the abutment foundation settlement of this problem,with the traditional technology of the high pressure jet grouting pile static grouting technology in reinforcing the quality and scope of application has a big advantage,in addition,with the high pressure jet grouting pile construction is convenient,fast construction speed,the peripheral features of small disturbance,based on the successful practice cases,introduces in detail,the application of the technology of the high pressure jet grouting pile,It has achieved the expected effect and provided important reference value for the same type of construction projects.
