As the increase of domestic high - rise buildings , more and more deep foundation trench supporting constructions have come into existence . among the general geographical condition of the urban district in qingdao , most of regions , which mainly consist of strong de composed rocks , are in quite good condition . except for the sandy soil and oozy soil along sea sides . but the development of rock cracks and breaking zones and unstable lamprophyre still exist , so blasting is needed during constructions of foundation trench . blasting have bad influence on the stability of slopes . moreover . the slope - liding has happened for several times , so the engineering project of foundation trench attracts more attention of people 隨著國內高層建筑的發展,深基坑支護工程越來越多,綜合青島市區的地質狀況,除海邊有砂性土及淤泥軟土外,大部分地域巖土條件相對較好,多以強風化巖為主,但巖石裂隙發育,間或有斷裂帶和穩定性極差的煌斑巖穿插其中,基坑施工時需要爆破施工,對邊坡的穩定造成了不利影響,加之連續出現的幾次滑坡失穩事件,基坑支護工程越來越引起了各方面的重視。
