低樁承臺
英文
low pile cap-
" 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。In the light of the low - lying pile cap foundations designed for main piers no. 2 and no. 3 of tianluo bridge on wenzhou - fuzhou railway. this paper describes the ways to resolve the construction problems of the foundations in deep water in sea and at seabed that is steep and without overburden, using the construction techniques of underwater rock blasting, steel cofferdam floating, positioning, bottom sealing and manual pile digging
摘要針對溫福鐵路田螺大橋2號、 3號主墩設計上採用低樁承臺基礎情況,介紹運用水下巖石爆破,浮運鋼圍堰就位、封底、人工挖孔樁等施工技術解決海上深水、河床陡峭且無覆蓋層的基礎施工難題。Low pile cap
深基礎低樁承臺The results indicate that this method can minish settlement largely, decrease level thrusts on bridge abutment, make the settlements transition, improve the bearing capacity of foundation soil and its economic benefits are notable. the results of field test show that low intensity piles can put into widely use in soft foundation of express way
研究結果表明,採用低強度樁復合地基加固橋頭軟基時,可以採用變樁長、變間距的設計思想,使沉降逐漸過渡,減輕橋頭跳車的危害,並且還可以減小沉降和深層土體水平位移,減小對橋臺及其樁基的水平推力,提高地基承載力。Secondly, considering the complexity of the analysis of inclined - loading pile, nonlinear finite element method is adopted to calculate the internal force and displacement of pile group under inclined loads, with the concept of equivalent width presented to simplify 3d problems into 2d problems. and a program is developed as well, which is able to consider the continuity, elastic - plasticity and layered characteristic of soil around the pile shaft. besides, the interactions among pile, base slab and soil are considered in this program and contact surface element is used to simulate slipping and crazing between pile and soil, or between base slab and soil under loads. then, the non - tension analysis is proposed, to reflect the low - tensile property of soil and concrete
在此基礎上,針對傾斜荷載下群樁基礎分析中的復雜性,提出採用非線性有限元對傾斜荷載下群樁的內力及位移進行分析,應用樁的等效寬度概念將空間問題簡化為平面問題考慮,並開發出能考慮樁周土介質連續性、彈塑性、分層性等因素的傾斜荷載下群樁內力及位移分析的計算機程序,並在程序中考慮了樁、土、承臺的相互作用,提出了採用接觸面單元來考慮荷載作用下樁與土體及承臺與土體間的滑移、開裂;並在此基礎上,提出了傾斜荷載下群樁基礎的「無拉力」分析方法,可有效地反映土體及混凝土材料的低抗拉特性。In view of the system complexity, it is difficult for a number of previous methods to consider the embedded cap effects on the dynamic pile - soil interaction system. as a result, the dynamic impedance of a pile group with embedded cap was rarely reported
由於系統的復雜性,以往樁-土動力相互作用研究的很多方法難以考慮承臺的埋置作用,因此有關埋置承臺(低承臺)群樁動力特性的研究報道很少。分享友人
