위해결재교후분사협층급경층등특수지질조건하응용정압법침장회출현폭장、침장곤난등문제，결합공정실례，제출료삼충해결방안。통과대기술、경제、공기진행대비론증득출，제고관장장신항압승재력적방식위최우선택。경검측，관장각항기술지표균만족설계요구。
It occurs blasting piles, settlement difficulties of pile or other issues on special geological conditions of thick silty sand dissection and hard formation by using the static pressure method. According to the problems motioned above, three kinds of solutions are put forward combined with engineering examples. Through contrastive demonstrating of the technology, economy and progress, it can be drawn that the method of strengthen the pipe in order to improve the compression bearing capacity of the pile body is the best choice. And the test results show that the piles can meet the design requirements of the technical indicators.
