Roadbed rigidity compensation construction method taking roadbed top surface design resilience modulus as target
The invention discloses a roadbed rigidity compensation construction method taking roadbed top surface design resilience modulus as a target. The roadbed rigidity compensation construction method comprises the following steps: measuring lower embankment top surface resilience modulus E0; calculating the difference En between the designed resilience modulus Ed and E0 of the top surface of the roadbed; according to the designed roadbed filling layer number, determining the rigidity compensation initial pseudo-resilience modulus Ei of each filling layer according to the principle that the rigidity compensation initial pseudo-resilience modulus Ei rises in sequence from the lower embankment to the top face of the roadbed, and according to the thickness of the filling layers and the corresponding filling layers Ei, the resilience modulus of filling materials in the corresponding filling layers is determined through a rigidity compensation design nomogram for filling. The problems that in the prior art, roadbed design depends on experience, construction quality is difficult to control, and a large number of paving test roads are needed for scheme verification are solved, an accurate andreasonable roadbed filling scheme is rapidly formulated according to roadbed design acceptance requirements and on-site filler supply conditions, the filling cost is greatly reduced, resource waste isreduced, and the engineering cost is reduced; the material utilization rate is improved, and the sustainable development environmental protection concept is practiced; meanwhile, the overall rigidityof the roadbed can be effectively improved, the roadbed field construction efficiency is improved, and long-term use of the roadbed is guaranteed.
本发明公开了一种以路基顶面设计回弹模量为目标的路基刚度补偿施工方法，包括测定下路堤顶面回弹模量E0；计算路基顶面设计回弹模量Ed与E0之差En；根据设计的路基填筑层数，按从下路堤至路基顶面依次升高的原则确定每一填筑层的刚度补偿初拟回弹模量Ei，根据填筑层的厚度及相应填筑层Ei，通过刚度补偿设计诺模图确定相应填筑层中填筑材料的回弹模量进行填筑。本发明克服了以往路基设计凭经验、施工质量难控制、需大量铺筑试验路进行方案验证的问题，根据路基设计验收要求和现场填料供应情况，迅速制定准确合理的路基填筑方案，大幅度降低填筑成本，减少资源浪费，降低工程造价，提高材料利用率，践行可持续发展环保理念；同时可以有效提升路基整体刚度，提高路基现场施工效率，为路基的长期使用提供保障。
