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
隨著國內高層建築的發展，
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。
The methods for the optimal design in the deep excavations are discussed, and the difference is compared between the traditional optimal methods and the modern ones, it safely conclude that the modern optimal methods overmatch the traditional ones

" prestress anchor ribbed beam support system " is a new practical support technology which came from soil nailing walls system and un - embedded rank of piles with anchors support system that has been used successfully for 4 years by the author and his company named qingdao deep foundation stabilization engineering co., ltd. it " s mechanism is similar to rank of piles with anchors support system that can not be inserted into the bottom of foundation trench, but it " s ribbed beams are used to replace rank of piles made before excavation so the work cycle can be shortened and the support system cost can be reduced ; meanwhile this system maintains the soil nailing wall " s convenience of digging and supporting
「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。
Abstract : this paper introduces the scheme, deep cut of foundation pit to bury pipe, which is adopted for wenjiayan seawall in qiantang rever. compared with the scheme of withstanding pipe, this scheme has the advantage of saving investment, simple construction and time + - saving. it is convenient to check the anti - seep installation between water pipe and seawall
