Abstract：
Introduction the 15~19 meter artificial drilled pile to pass through 5~8 meter thick the silty clay layer, silt pile bottom has been disturbed, Envelope within the base to the foundation piles within the slope instability, The nearby ground presented the subsidence of the earth. Through the construction of technical design envelope compared, Using a no-Rachel (cantilever) retaining structure Program integrated support. Made good technical and economic effect. Moreover, use of compaction grouting, improving soil structure. using short template, High strength rapid set concretes protection wall construction methods, finally solved the technical problem.
DING Si-Chi. Through silty clay layer of filling pile and box shape compound foundation key technologies design and construction[J]. Architecture Technology, 2011, 42(08): 731-732.
