为了保证在地基强夯时的准确程度,需要对其进行多方面的检测以保证效果,下边小编就来为您介绍关于多种关于试验检测的相关方式,继续往下看吧:
In order to ensure the accuracy of foundation dynamic compaction, it needs to be tested in many aspects to ensure the effect. The following Xiaobian will introduce you to a variety of relevant methods of test and detection. Continue to read:
1、负载试验,在强夯工程竣工后,在基础结构质量检测中,如果技术人员采用荷载试验的试验方法,首先检查的是强夯地基结构的承载力和变形速率。
1. Load test: after the completion of the dynamic compaction project, in the quality inspection of the foundation structure, if the technician adopts the test method of load test, the first thing to check is the bearing capacity and deformation rate of the dynamic compaction foundation structure.
2、标准贯入试验,对于此试验方式,首先,SPT的应用方案侧重于由粉土、粉土和粘土组成的强夯地基。采用标准砖入渗试验方法检测地基结构的稳定性、密度和泥沙的变形参数。结合标准入渗试验方法和荷载试验方法,对地基承载力和加固深度进行了检测,并对液化地基的去除效果进行了评价。
2. Standard penetration test. For this test method, firstly, the application scheme of SPT focuses on the dynamic compaction foundation composed of silt, silt and clay. The standard brick infiltration test method is used to detect the stability, density and sediment deformation parameters of the foundation structure. Combined with the standard infiltration test method and load test method, the foundation bearing capacity and reinforcement depth are tested, and the removal effect of liquefied foundation is evaluated.
3、静态检测实验,与标准贯入试验方法类似,静力触探试验适用于粘土、粉土和含砾石较少的粉土。采用强夯法检测强夯地基时,先检测地基结构的特殊侵彻、锥阻力和孔隙水压力。
3. The static test is similar to the standard penetration test method. The static cone penetration test is applicable to clay, silt and silt with less gravel. When the dynamic compaction method is used to detect the dynamic compaction foundation, the special penetration, cone resistance and pore water pressure of the foundation structure shall be detected first.
4、动态检测实验,动力触探是以强风化硬岩、软岩、砂土、砂砾土等地基土为基础的强夯地基的佳选择,要通过地基试验来表现地基土的孔隙度、密实度、强度和变形参数。采用动力触探法检测强夯地基的质量,通过对场地均匀性的评价,得出地基的加固效果。
4. Dynamic detection experiment: dynamic penetration test is a good choice for dynamic compaction foundation based on strongly weathered hard rock, soft rock, sandy soil, sandy gravel soil and other foundation soil. The porosity, compactness, strength and deformation parameters of foundation soil should be expressed through foundation test. The dynamic penetration method is used to detect the quality of dynamic compaction foundation. Through the evaluation of site uniformity, the reinforcement effect of foundation is obtained.
以上就是关于对强夯地基施工时的相关检测方法,希望以上的内容会对您有一定的帮助,更多相关的信息小编会陆续的整理发布到网站上,感谢您的观看。
