30、ructures with aminimum of disruption to surface activities or disturbance to surface and near surfacestructures developed in the 1960s as an outgrowth of pipe jacking. During the pastthirty years, this method has been used to install increasingly larger undergroundopenings in confined urban environm

31、ents, particularly in Europe and Asia. Typicalprojects include pedestrian walkways beneath busy roads, drainage structures beneathroads and railroads, and short vehicular tunnels beneath highways and railroads. Thetypical competing method of construction for these projects is the cut-and-covermethod

32、.Use of the method in the United States, to date, has been limited. However, theI-90/I-93 Interchange of the Central Artery Project, which is currently underconstruction, will be one of the largest, 12 m high by 25 m wide by up to 110m long,and most complex jacked tunnel projects in the world. The i

33、nterchange tunnels willbe constructed under eight rail lines serving South Station in Boston, comprising oneof the busiest commuter rail areas in the Northeast.The objective of this publication is to provide information on the design, construction,and monitoring of jacked tunnels to assist owners an

36、s early days of smallsection tunnels (100 sq.ft. face or less), through to the current day when tunnels witha face area in excess of 3000 sq.ft. are being installed. The development will beillustrated using a selection of design details, diagrams, and construction photographs.Tunnel jacking is a ter

37、m which refers to the installation of tunnels by pushing theminto the ground while excavating from an open face. The tunnels, which are usuallyof rectangular cross section, are installed beneath a facility which cannot be removedor which the facility owner does not wish to be removed. This technique

38、 can be usedfor relatively small sections (6ft x 6ft) up to large, full size highway sections (80ft x40ft) in lengths up to several hundred feet.The technique developed from pipe jacking when the circular sections available wereeither too small or inefficient for the final use of the tunnel. The tec

39、hnique is mostoften used in soft ground and at shallow depth. It has been used successfully in avariety of ground conditions, including soft clays, granular material, filled ground andmixed ground. It is a specialist technique which requires a clear and preciseunderstanding of the inter-relationship

40、 between design and construction, and perhapsfor this reason it has been carried out by a relatively small number of contractorsaround the world. The contractors often have their own preferred methods ofinstalling the tunnels. Some of the methods and/or the equipment used are patentedby individual o

41、rganizations, although there are usually several alternative methods anddetails which can be used.Although it is not the solution in all situations where a tunnel or underbridge isrequired beneath a facility, it is certainly an approach which should be considered inmany applications and often provid

44、 AND CONSTRUCTIONconstructed by cut-and-cover methods. It is a technique which evolved from pipejacking and retains many of the same features as pipe jacking. Pipe jacking wasintroduced on the Northern Pacific Railroad in the late 1890s as a method forinstalling culverts without severe disruption to

45、 the overlying rail service.1The development from pipe jacking to tunnel jacking was made in the 1960s whenthe circular pipe jacked sections were found to be either too small or were inefficientfor their intended purpose. At that time, contractors started to jack rectangularsections. These were typi

46、cally reinforced concrete, pre-cast off site. In the 30 or soyears since those early days, the technique has developed significantly and nowincludes a wide variety of possible end products, ranging from 3m square (10ftsquare) rectangular pedestrian subways installed beneath busy roadways, to 25m wid

47、ex 12m high (80ft x 40ft) monolithic rectangular tunnel sections to accommodate fullwidth and height clearance highway traffic beneath operating rail tracks, roads, rivers,or airport runways.The technique has also been used to install relatively small tunnel sections withinwhich concrete foundations

48、 can be constructed in readiness to receive a bridgesuperstructure. This can either be jacked into position with no disruption to theoverlying facility operations, or slid into position during a limited possession of theoverlying facility. Superstructures installed by this method have included simpl

49、ysupported spans, multi-span bridges and portal frame bridges. Large skews have beenaccommodated.Tunnel jacking has been used in many parts of the .world, including Europe(particularly in the UK and Germany), Australia, India, South Africa, and Canada. Ithas been used extensively in the Far East, particularly in Japan. It is not a techniquewhich has been used to any significant extent in the USA to date, although a fewtunnels have been jacked in California over the past 10 years or so. The I-90/I-93Interch
