Faced with very soft soils onboth the Lijin and Zhanhua WindFarms in China, Guohua Ruifeng(Zhanhua) Wind Power Ltddecided to use a Tensar TriAxTM
Mechanically Stabilised Layer toenable the heavy vehicles to gainaccess to both sites.The foundation soils on theZhanhua project were excavatedfrom the nearby shrimp pondsand so the project provedparticularly challenging. TensarTechnology proved to be theideal solution to overcome theseconstruction issues.
TriAxTM geogrids are used to create a mechanically stabilised layer in the construction of an access road at Dongying WindFarm, in China.
Tensar TriAxTM geogrids were theanswer for a new Scottish windfarm built in a rural area. Existingtracks had to be widened and newaccess roads built over the sitewhich had low ground strengthwith CBR values between 0.5%and 1%. Using thick stone layersto accommodate site traffic wouldhave involved large numbers ofvehicle movements and excessiveroad settlement. Instead, multipleTensar TriAxTM geogrid layers wereinstalled and combined with site-won stone. Although the stonequality was less than ideal, thissolution delivered excellenttrafficking performance andachieved a significant carbonemissions saving over anunreinforced solution.

Working with the wind energy industry -developing construction solutions
Reducing construction CO2 emissions
The greatest challenge when the wind farm is being constructed can bewhen the large turbine components are unloaded and lifted into positionusing a crane. The load spreading capability of a Tensar mechanicallystabilised layer increases the bearing capacity of working platforms forheavy-duty plant, cranes and piling rigs. For the contractor this means thatless natural aggregate is required to construct the platform which canresult in quicker construction and less cost when compared with atraditional unreinforced construction.
Heavily loaded areas
Stable access roads andworking platforms
By using a Tensar mechanically stabilised layer in a road or working area, constructionsavings of up to 50% can be made in the amount of aggregate required. This meansthat the project can run more efficiently, as less excavated material needs to be takenaway from site and less aggregate needs to be imported, placed and compacted.
On a wind energy project, material often needs to be transported considerabledistances to and from the site. By reducing vehicle movements and the volume ofmaterial to be removed from the site, considerable savings of up to 50% can be madein construction CO2 emissions, when compared with an unreinforced design. TensarInternational Ltd published the TriAxTM Carbon Calculator in 2009, this was developedand checked by Coffey Geotechnics.
Armed with an Application Suggestion from Tensar, the user can enter the details andprint out a statement which shows the percentage saving in CO2 emissions whencompared with the unreinforced design.
The TriAxTM Carbon Calculator is available at www.tensarsustain.co.uk
Temporary structures are economical and practicalEarth retaining structures required on wind energy sitesneed to be practical, economical to build and use fillmaterials which are available locally to the site wherepossible. The Tensartech TR2 System is often used as itrequires no formwork since the steel mesh face is secured
as the geogrid and reinforced fill materials are placed.Structures up to 18m have been constructed with thissystem at a lower cost than that of traditional methods.The face is normally vertical, but inclined face angles canalso be accommodated by the system.
Staging areas for offshore wind developmentsThe construction of offshorewind farms often requires astaging area onshore for thedelivery or assembly of largepieces of equipment. Thesestaging areas are oftenconstructed on weak ground, sothe bearing capacity has to beincreased and designed for safesite operations, TensarTechnology is a proven, practicalsolution in overcoming suchproblems.
There are now unprecedented demands to designeconomic and environmentally sensitive roads andworking areas sited over weak or variable ground. Theseroads are usually required for the construction,maintenance and ultimately the dismantling phases of awind farm project.
Excavating organic material such as peat is often difficult,time consuming, expensive and releases significantquantities of CO2. Tensar geogrids offer an alternative highperformance solution.
The structural contribution made by Tensar TriAxTM
geogrids is to reinforce the unbound layers of roads andtrafficked areas to create a mechanically stabilised layer.Aggregate particles interlock with the geogrid and areconfined within the stiff geogrid apertures, creating anenhanced composite material with improved performancecharacteristics.
A mechanically stabilised layer incorporating TriAxTM
geogrids can combine major cost savings withconsiderable performance benefits in granular capping,sub-base and other aggregate layers.
When compared with an unreinforced aggregate layer, amechanically stabilised layer incorporating TriAxTM
geogrids can:
■ Give savings in granular thickness of up to 50% with no performance loss
■ Provide a reduction of excavated soil together with conservation of natural aggregates
■ Control differential settlement
■ Reduce disturbance and weakening of sensitive subgrade formations
■ Improve fill compaction
■ Increase design life
■ Increase bearing capacity
■ Give savings of up to 50% on constructionCO2 emissions
Additional benefits can include:
■ A low cost retaining wall at a fraction of the cost of a reinforced concrete solution
■ Rapid and economical construction
■ Often no specialist construction skills necessary
■ Simple to build using established earth embankment construction techniques
■ Possibility of using site-won including cohesive or contaminated materials
■ High tolerance of differential settlement
■ For Temporary Works it can either be easily dismantled or covered with backfill
■ Ready for immediate use upon completion
■ High tolerance to seismic loadingTensartech Earth Retaining Systems allow rapid construction of bridge abutments and retaining walls.(Photography courtesy of Forestry Commission, Scotland).
