Long-distance riverway concrete retaining wall riprap foundation bearing capacity detection method
The invention discloses a long-distance riverway concrete retaining wall riprap foundation bearing capacity detection method. The long-distance riverway concrete retaining wall riprap foundation bearing capacity detection method can detect the bearing capacity of a riprap foundation frequently and repeatedly, and is high in speed, low in cost, simple, convenient and feasible. According to the technical scheme, the long-distance riverway concrete retaining wall riprap foundation bearing capacity detection method comprises the steps that when the riprap foundation is laid, stone blocks are arranged in order, the virtual laying thickness is controlled to be 50 cm, and holes are filled and leveled up with the stone blocks with reasonable gradation; a road roller is used for strong vibration four times, then elevation points are distributed, the distributed elevation points are measured once again after strong vibration, and construction of the upper layer is carried out after the settlement amount is smaller than 3 cm; the thickness of the last layer is controlled according to the designed elevation, the virtual laying thickness is not larger than 50 cm, and rolling compaction is stopped when the settlement difference of two times of compaction is smaller than 5 mm; and during detection, 20 detection points are uniformly arranged in each 100m length range, the average number of theheight differences of two times before and after each detection point is used as the settlement difference in the detection length range, and the height difference of a single detection point does not exceed 30% of the average number.
长距离河道混凝土挡土墙抛石基础承载力检测方法是一种承载力的检测方法，本发明提供了一种可以对抛石基础承载力频繁、多次检测的方法，速度快，费用低，简便易行。其所采用的技术方案是：抛石基础铺筑时将石块排列整齐，虚铺厚度按50cm控制，其上用级配合理的石块将孔隙填平。用压路机强振4遍后布设高程点，每再强振一遍测量布设的高程点一次，直到沉降量小于3cm后，进行上一层施工。最后一层厚度以设计高程控制，虚铺厚度不大于50cm，当两次压实的沉降量差小于5mm时停止碾压。检测时，每100m长度范围内均匀设置20个检测点，以每个检测点前后两次高差的平均数作为检测长度范围内的沉降量差，单个检测点的高差不超过平均数的30％。
