基礎(chǔ)和堤壩支撐系統(tǒng)
解決方案概述
當(dāng)面對(duì)軟弱或多變的地基土?xí)r，路堤或回填區(qū)的建設(shè)將面臨技術(shù)上的挑戰(zhàn)且代價(jià)高昂。Tensar有一系列加固路堤基礎(chǔ)的解決方案，以創(chuàng)建牢固的結(jié)構(gòu)，使荷載更均勻地分布在軟土地基上，并加強(qiáng)路堤防止破壞。這些系統(tǒng)減少了差異沉降，減少了回填量。它們可以實(shí)現(xiàn)單級(jí)施工，大大縮短了施工流程。
坦薩相比競(jìng)爭(zhēng)對(duì)手如何?
Tensar的基礎(chǔ)和堤壩產(chǎn)品是經(jīng)過(guò)驗(yàn)證的高性能解決方案，比其他解決方案具有顯著的優(yōu)勢(shì)。

高強(qiáng)土工布
- Reduces lateral stress on the subgrade, but requires substantial subgrade settlement to mobilise reinforcement effect
- Over weak soils, placement of the first fill layers over the geotextile can be difficult, requiring lightweight plant. Compaction cannot commence until a reasonable amount of fill is in place
- As embankment construction progresses, settlements under the thicker centre section are considerably greater than at the edges, often requiring staged construction to allow pore pressures to dissipate

TensarTech Stratum
- Created a 1m or 1.3m deep stiff foundation platform that mitigates settlement as well as reduce lateral stress on the subgrade
- When filled with aggregate Stratum provides a sturdy working platform for placement and compaction of the embankment fill, even over the weakest soils
- By distributing load, the stiff Stratum mattress reduces differential settlement across the base increases bearing capacity, enabling a more rapid embankment construction

樁基礎(chǔ)
- Often requires construction of a working platform across the site to provide safe access and operation of heavy piling equipment
- Typically, higher cost than Stratum foundation with higher mobilisation costs.
- Multiple stage operation - working platform construction, pile installation, pile caps or slab construction and curing time.

TensarTech Stratum
- No heavy plant required to access over the weak soil. Transport, filling and compaction all takes place over the filled mattress sections.
- Typically, a lower cost solution than piled foundations with low mobilisation costs. No specialist skills required to assemble the mattress
- A single stage installation process with no specialist skills required to assemble the mattress

傳統(tǒng)未加筋堤壩
- Design often by third party engineer
- Over weak soils, placement of the first fill layers can be difficult, requiring lightweight plant. Compaction cannot commence until a reasonable amount of fill is in place
- As embankment construction progresses, settlements under the thicker centre section are considerably greater than at the edges, often requiring staged construction to avoid overstressing the subgrade and to allow pore pressures to dissipate.

TensarTech Stratum
- Full design supply solution available from Tensar. One-source supply of all components
- When filled with aggregate Stratum provides a sturdy working platform for placement and compaction of the embankment fill, even over the weakest soils
- By distributing load, the stiff Stratum mattress reduces differential settlement across the base increases bearing capacity, and reduces lateral strains in the subgrade, enabling a more rapid embankment construction
