摘　　要：依托娄新高速K22+200～K22+400段右侧边坡支护工程,通过现场施工、选点监测、有限元分析等过程研究炭质泥岩夹层边坡的治理方法与稳定性分析。依据工程地质资料,对比分析选取"锚杆+抗滑桩+灌浆加固"的方法进行边坡治理,并布设监测点进行对边坡的水平和竖向位移进行监测。然后,采用有限元对边坡进行稳定性进行分析。研究结果表明:加固后的边坡安全系数为1.6,并且对比现场监测点与有限元分析的位移过程,验证了有限元分析结果的可靠性。Depending on the right slope supporting construction of Lou - Xin high - speed of the K22 and 200 K22 and 400 section, the treatment method and stability analysis of carbonaceous mudstone interlayer were ana-lyzed by site operation, site monitoring at selected points and finite element analysis. Based on engineering geolog- ical data, the slope treatment suggestion anchor and anti - slide pile together with grouting was selected after comparative analysis, and monitoring points were layed out on slope to monitor the horizontal and vertical displacement of the slope. Then, finite element method was employed to investigate the stability of slope. The re sults show that the reinforced slope safety factor is 1.6. The reliability of finite element results is demonstrated by comparing the deformation of selected points through site monitoring with that in the process of finite element a nalysis.
