Treatment method of settlement of high-speed railway roadbeds in soft-soil areas
The invention discloses a treatment method of the settlement of high-speed railway roadbeds in soft-soil areas. The treatment method comprises the following steps: firstly, reinforcing and strengthening the foundation of a high-speed railway roadbed; and then, reinforcing and strengthening the side slopes or the ground of the high-speed railway roadbed. In the step of reinforcing and strengthening the foundation of the high-speed railway roadbed, a plurality of rows of rotary jet grouting piles are constructed among original pile foundations at slope toes of a conventional high-speed railway roadbed for performing reinforcement and strengthening. In the step of reinforcing and strengthening the side slopes or the ground of the high-speed railway roadbed, grouting holes are formed in the side slopes or the ground of the conventional high-speed railway roadbed; perforated grouting pipe are inserted in the grouting holes; the seriflux is injected in the perforated grouting pipe, so that the reinforcement and the strengthening are completed. The treatment method of the settlement of high-speed railway roadbeds in soft-soil areas, provided by the invention is safe, reliable, scientific and reasonable, and low in cost. Through the adoption of the treatment method, the settlement of roadbeds is effectively controlled, and influence caused by the settlement of roadbeds on conventional roadbed structures and the surrounding environment is reduced.
