    「預應力錨桿肋梁支護技術」是筆者及所在單位歷時四年在土釘墻和無嵌入多錨排樁兩種支護體系基礎上開發應用成功的一種新型實用性支護技術。其支護機理類似於未嵌入坑底的排樁多錨支護,只是由肋梁代替了開挖前施工的排樁從而提前工期並降低支護造價;同時繼承了土釘墻隨挖隨支護的機動靈活性。自1998年至今該技術已在青島、濟南、煙臺等十幾個深基坑和高邊坡工程中成功應用。

  3. A brief introduction is given to the treatment of the zeya dam foundation, principles of seepage control and design of the concrete face rockfill dam of the zeya reservoir. as for the excavation of the sand - gravel zones, except the toe slab and its 1 / 9 bottom width down stream, the alluvial layers are excavated to the micro - weathered rocks, while the other sections remain unexcavated. regarding to the treatment of the fracture zones, concrete filling is used for the toe slabs and semi - permeable materials are used for other section. according to the construction characteristics, a filter is placed in the down stream embankment foot. to improve the integrity of the dam foundation and anti - seepage capability consolidation grouting and curtain grouting are adopted. as a result safety, economic benefit, convenience in construction and good performace are achieved
