Investigation of soil is of primary importance in the construction sector. It is necessary before building a new structure to prevent the failure of the foundations at a later stage. Bearing capacity of soil and the soil must be established to determine whether the stability of the foundation can be obtained. This is necessary because the gaps in the foundation structures are almost irreparable.
Soil investigation is gaining popularity and people are learning from its mistakes. We insist on a certificate from a structural engineer to study the soils of each property being developed. This investigation has not been followed in rural areas for low-rise structures, and it should be made popular by education consultants and persons on technical requirements and financial benefits of soil investigation.
Investigation of soil is of paramount importance in any construction project. In most developed countries soil study for the projects on the development of roots is required, and is performed by expert laboratories. In Iraq, on many projects of low amplitude, consultants decide to lift the safe capacity of soil by simple observation and experience. This is very inaccurate, and the bearing capacity of safety such circumstances is either on the upper side or on the lower side of the actual value.
In the first case of the SBC expects to be on the lower side, the structure begins to fall and becomes dangerous to use in a short period of time. In the second case, the foundation is too strong and therefore not profitable. There is evidence that the investigation of soil test, if it is performed, even in smaller projects, may lead to economic and safe structures.
The factors that determine the feasibility of soil for railways, road, airport projects and the sea link. swelling index, the bearing capacity, liquid limit, plastic limit, MDD, finding a maximum compaction tests are usually carried in railway and road projects. soil improvement should be taken to overcome a deficiency. It usually occurs in the areas where higher roads, slope stabilization should be achieved by using the geo-membrane or nets of debris. In the case of black cotton soil swelling takes place that must be rectified by providing band drains. If no structure exists, but the load is important on the ground below, for example, construction of container yards, the ground below should be strengthened.
Latest technology and innovations in the soil investigation.
Almost all the latest techniques available internationally in the ground by the survey are available. There are several laboratories with automated equipment for soil test. These facilities reduce the possibility of soil test.
Errors and improve the reliability of the results significantly. Here are some tests that require reading to be taken intermittently over a period of seven days. It will not be possible unless the machine is fully automated and computerized. Discovering safe bearing capacity by methods such as plate load test, cutting basic standard penetration test. Second, stacking - pile end will be used in case of high loads. Thirdly, in the case of an expansive soil swelling index is to be found.
The problems encountered in the investigation of the soil.
In the soil investigation, when we have big rocks, while annoying, it is difficult to determine the degree of original rock. To get the level of original rock, we change the location of drill or we continue with the drilling until the actual level of rock is obtained. In CBR, sometimes 5mm CBR penetration is greater than the value of 2.5 mm penetration CBR. We move the test site to obtain the correct value of CBR.
These are integrity, accreditation of test facilities, test speed and technical competence. Specialized services include services for new construction, assessment of existing structures, investigation and failure analysis, expertise and instrumentation testing, assessment of building materials, repair and rehabilitation Heritage Conservation and Research & Development.
