EMBANKMENT
LoadCap allows the design of ROAD and RAILWAY EMBANKMENTS. The verifications performed include: Ultimate Load, Settlements (3D), Settlement over time, Consolidation with gravel piles, and Drainage. It is also possible to reinforce the soil with geosynthetics.

Excellent product.
To make it an outstanding software, the Skempton & Bjerrum method could be added to the settlement calculation, which calculates both elastic and consolidation settlements simultaneously. Additionally, for each layer, it would be interesting to directly input the void ratio-log P curve from the oedometer tests, so that the software can automatically select the value of the oedometer modulus Eed in the load range of the considered layer, between the existing lithostatic stress and the increase in the normal stress component induced… but this is just a wish of mine, as I have not been able to find software with such features on the market.

Calculation of oedometer settlements from oedometer test
In the added stratigraphy data, the following should be included:
RR: Recompression ratio
CR: Compression ratio
OCR: Overconsolidation ratio
Assign with reference to: Parameters RR, CR
Loadcap will calculate the oedometer settlements considering (RR, CR of the oedometer curve) the preconsolidation and normal consolidation phase based on the OCR value.

Las versiones mas antiguas, permitían poner el factor de seguridad, y en los resultados y gráficas se apreciaba muy bien las capacidades de carga ADMISIBLES.
Lo que resultaba muy útil, sobre todo en cálculos simplificados por la teoría clásica. Esta modalidad ya no esta disponible en las ultimas versiones, donde te da solo la capacidad de carga ultima.

,la vercion 2018 es la mejor vercion de todas la verciones, quede maravillado con esa vercion, sin embargo la vercion 2020 requiere muchas reviciones no brinda el exelente servicio que da load cap 2018 , sugeriria hacer una revicion en la importacion de archivos dwg y los archivos de txt en la vercion 2020 ya que los iconos ya no estan y es menos intuitivo que en la vercion anterior poder acceder a esta parte , en general e cuanto a los alculos y a las memorias de las mismas ambos son exelentes en ese sentido

I am unable to use the program to determine the settlement according to Pradel method. The User’s Manual does not provide sufficient detail for this.

Hi Reynaldo,
Below an excerpt of the algorithm used by loadcap I hope it will be useful

Yesterday I’ve purchased one Loadcap license for our office in New Zealand and I want to purchase a second license for our office in Australia. I’m responsible for both invoices. My address is: …… Group Ltd, 105 …., Newmarket, …., New Zealand.
Can you please explain how I can purchase the 2nd license? The address for our second license is: …… Ltd, Kings Technology Park, Ground Floor, ….., Southbank, …..

Message: An excellent software with the recent specification under Eurocode 7 at a reasonable price.

LoadCap represents a “milestone” in the geotechnical field for checking the bearing capacities and the settlement of superficial foundations.
I personally use this software since 2000, I have seen it grow, implement, improve and, above all, promptly update to new regulations and requirements suggested by the different users.
It is a truly professional and very intuitive program.
Denis Moore (verified owner) –
Complete software for verification of bearing capacity and superficial foundation settlements.
It is very useful the input of every layer geotechnical parameters
Very useful the Input of the geotechnical parameters of each stratum provided dynamic and static GeoStru software, with processing executed through a specific export file.
It allows verification of many geometries of foundations, insertion of reinforcements, checking pressure bulbs with influence on adjacent load pressure bulbs, and liquefaction checks.
Calculation of edometric and elastic settlements using various methodologies, among the most used Terzaghi and monodimensional consolidation. Schmertmann, Burland, elasticity theory.
The plug-in for checking the settlement of earth embankments is very useful.
I think it’s a great professional program
