基础和堤坝支撑系统
解决方案概述
当面对软弱或多变的地基土时，路堤或回填区的建设将面临技术上的挑战且代价高昂。Tensar有一系列加固路堤基础的解决方案，以创建牢固的结构，使荷载更均匀地分布在软土地基上，并加强路堤防止破坏。这些系统减少了差异沉降，减少了回填量。它们可以实现单级施工，大大缩短了施工流程。

高强土工布
- 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

桩基础
- 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

传统未加筋堤坝
- 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
