为更有效地对软土质堤防进行加固处理，将布袋注浆技术和可控性压密注浆桩技术融为一个整体，形成一项新的软土地基处理技术———导水布袋复合压密注浆桩技术。该技术利用布袋的良好导水性，有效解决了软土在压密注浆处理过程中，超孔隙水压力消散过慢的技术难题。将导水布袋复合压密注浆桩技术应用于洞庭湖软土质堤防加固试验处理，通过对处理前后的原状土进行标准贯入试验，对桩和桩间土进行取芯检测以及施工结束后位移观测、现场回访等，分析论证了导水布袋复合压密注浆桩技术对软土质堤防的加固效果。在加固处理一年后，监测结果表明，堤防侧向位移量趋于收敛，堤基已处于稳定状态。

In order to reinforce soft soil embankment more effectively ,bag grouting and controllable pressure grouting pile technique were combined to develop a new treatment measure of soft soil foundation ,namly ,condensed grouting pile with drainage bag lining .With this technique ,the favorable hydraulic conductivity of the cloth bags was taken advantage of to solve the problems of slow pore water pressure dissipation in the grouting process of soft soil .Here this technique was adopted in the reinforcement treatment test of Dongting lake soft soil embankment .Based on the standard penetration tests of the undisturbed soil before and after the treatment ,the detection of core soil of the pile and between the piles ,as well as the displacement observation and site investigation after the construction was completed , the reinforcement effect of condensed grouting pile with drainage bag lining technique was analyzed and demonstrated .One year after the reinforce-ment ,the monitoring results of the embankment indicate that the literal displacement is diminishing ,the foundation of the embankment is stable .
